Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79040, here are decompositions:

  • 61 + 78979 = 79040
  • 139 + 78901 = 79040
  • 151 + 78889 = 79040
  • 163 + 78877 = 79040
  • 349 + 78691 = 79040
  • 397 + 78643 = 79040
  • 433 + 78607 = 79040
  • 457 + 78583 = 79040

Showing the first eight; more decompositions exist.
