Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617062, here are decompositions:

13 + 31617049 = 31617062
223 + 31616839 = 31617062
313 + 31616749 = 31617062
439 + 31616623 = 31617062
523 + 31616539 = 31617062
541 + 31616521 = 31617062
643 + 31616419 = 31617062
661 + 31616401 = 31617062

Showing the first eight; more decompositions exist.
