Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517362, here are decompositions:

89 + 31517273 = 31517362
131 + 31517231 = 31517362
389 + 31516973 = 31517362
521 + 31516841 = 31517362
659 + 31516703 = 31517362
743 + 31516619 = 31517362
839 + 31516523 = 31517362
983 + 31516379 = 31517362

Showing the first eight; more decompositions exist.
