Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724450, here are decompositions:

  • 13 + 8724437 = 8724450
  • 29 + 8724421 = 8724450
  • 73 + 8724377 = 8724450
  • 79 + 8724371 = 8724450
  • 103 + 8724347 = 8724450
  • 127 + 8724323 = 8724450
  • 131 + 8724319 = 8724450
  • 139 + 8724311 = 8724450

Showing the first eight; more decompositions exist.
