Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1430, here are decompositions:

  • 3 + 1427 = 1430
  • 7 + 1423 = 1430
  • 31 + 1399 = 1430
  • 103 + 1327 = 1430
  • 109 + 1321 = 1430
  • 127 + 1303 = 1430
  • 139 + 1291 = 1430
  • 151 + 1279 = 1430

Showing the first eight; more decompositions exist.
