Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517084, here are decompositions:

73 + 31517011 = 31517084
103 + 31516981 = 31517084
307 + 31516777 = 31517084
331 + 31516753 = 31517084
457 + 31516627 = 31517084
541 + 31516543 = 31517084
601 + 31516483 = 31517084
661 + 31516423 = 31517084

Showing the first eight; more decompositions exist.
