Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724372, here are decompositions:

  • 43 + 8724329 = 8724372
  • 53 + 8724319 = 8724372
  • 61 + 8724311 = 8724372
  • 71 + 8724301 = 8724372
  • 79 + 8724293 = 8724372
  • 89 + 8724283 = 8724372
  • 103 + 8724269 = 8724372
  • 109 + 8724263 = 8724372

Showing the first eight; more decompositions exist.
