Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514582, here are decompositions:

3 + 31514579 = 31514582
31 + 31514551 = 31514582
103 + 31514479 = 31514582
109 + 31514473 = 31514582
163 + 31514419 = 31514582
181 + 31514401 = 31514582
433 + 31514149 = 31514582
439 + 31514143 = 31514582

Showing the first eight; more decompositions exist.
