Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483282, here are decompositions:

53 + 31483229 = 31483282
113 + 31483169 = 31483282
443 + 31482839 = 31483282
449 + 31482833 = 31483282
461 + 31482821 = 31483282
503 + 31482779 = 31483282
521 + 31482761 = 31483282
599 + 31482683 = 31483282

Showing the first eight; more decompositions exist.
