Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617182, here are decompositions:

109 + 31617073 = 31617182
409 + 31616773 = 31617182
433 + 31616749 = 31617182
613 + 31616569 = 31617182
643 + 31616539 = 31617182
661 + 31616521 = 31617182
673 + 31616509 = 31617182
823 + 31616359 = 31617182

Showing the first eight; more decompositions exist.
