Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70380, here are decompositions:

  • 7 + 70373 = 70380
  • 29 + 70351 = 70380
  • 53 + 70327 = 70380
  • 59 + 70321 = 70380
  • 67 + 70313 = 70380
  • 71 + 70309 = 70380
  • 83 + 70297 = 70380
  • 109 + 70271 = 70380

Showing the first eight; more decompositions exist.
