Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157892, here are decompositions:

  • 3 + 157889 = 157892
  • 61 + 157831 = 157892
  • 79 + 157813 = 157892
  • 223 + 157669 = 157892
  • 313 + 157579 = 157892
  • 331 + 157561 = 157892
  • 349 + 157543 = 157892
  • 373 + 157519 = 157892

Showing the first eight; more decompositions exist.
