Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560254, here are decompositions:

  • 3 + 31560251 = 31560254
  • 7 + 31560247 = 31560254
  • 157 + 31560097 = 31560254
  • 181 + 31560073 = 31560254
  • 277 + 31559977 = 31560254
  • 421 + 31559833 = 31560254
  • 433 + 31559821 = 31560254
  • 577 + 31559677 = 31560254

Showing the first eight; more decompositions exist.
