Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294998990, here are decompositions:

  • 53 + 4294998937 = 4294998990
  • 167 + 4294998823 = 4294998990
  • 193 + 4294998797 = 4294998990
  • 281 + 4294998709 = 4294998990
  • 349 + 4294998641 = 4294998990
  • 421 + 4294998569 = 4294998990
  • 433 + 4294998557 = 4294998990
  • 631 + 4294998359 = 4294998990

Showing the first eight; more decompositions exist.
