Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724402, here are decompositions:

  • 31 + 8724371 = 8724402
  • 73 + 8724329 = 8724402
  • 79 + 8724323 = 8724402
  • 83 + 8724319 = 8724402
  • 101 + 8724301 = 8724402
  • 109 + 8724293 = 8724402
  • 139 + 8724263 = 8724402
  • 149 + 8724253 = 8724402

Showing the first eight; more decompositions exist.
