Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72570, here are decompositions:

  • 11 + 72559 = 72570
  • 19 + 72551 = 72570
  • 23 + 72547 = 72570
  • 37 + 72533 = 72570
  • 67 + 72503 = 72570
  • 73 + 72497 = 72570
  • 89 + 72481 = 72570
  • 101 + 72469 = 72570

Showing the first eight; more decompositions exist.
