Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1486, here are decompositions:

  • 3 + 1483 = 1486
  • 5 + 1481 = 1486
  • 47 + 1439 = 1486
  • 53 + 1433 = 1486
  • 59 + 1427 = 1486
  • 113 + 1373 = 1486
  • 167 + 1319 = 1486
  • 179 + 1307 = 1486

Showing the first eight; more decompositions exist.
