Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484602, here are decompositions:

59 + 31484543 = 31484602
89 + 31484513 = 31484602
239 + 31484363 = 31484602
263 + 31484339 = 31484602
509 + 31484093 = 31484602
521 + 31484081 = 31484602
683 + 31483919 = 31484602
719 + 31483883 = 31484602

Showing the first eight; more decompositions exist.
