Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551714, here are decompositions:

31 + 31551683 = 31551714
43 + 31551671 = 31551714
101 + 31551613 = 31551714
127 + 31551587 = 31551714
137 + 31551577 = 31551714
167 + 31551547 = 31551714
197 + 31551517 = 31551714
211 + 31551503 = 31551714

Showing the first eight; more decompositions exist.
