Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542542, here are decompositions:

  • 3 + 33542539 = 33542542
  • 53 + 33542489 = 33542542
  • 179 + 33542363 = 33542542
  • 281 + 33542261 = 33542542
  • 353 + 33542189 = 33542542
  • 389 + 33542153 = 33542542
  • 431 + 33542111 = 33542542
  • 479 + 33542063 = 33542542

Showing the first eight; more decompositions exist.
