Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517002, here are decompositions:

29 + 31516973 = 31517002
113 + 31516889 = 31517002
191 + 31516811 = 31517002
383 + 31516619 = 31517002
389 + 31516613 = 31517002
431 + 31516571 = 31517002
443 + 31516559 = 31517002
479 + 31516523 = 31517002

Showing the first eight; more decompositions exist.
