Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551702, here are decompositions:

19 + 31551683 = 31551702
31 + 31551671 = 31551702
73 + 31551629 = 31551702
89 + 31551613 = 31551702
103 + 31551599 = 31551702
109 + 31551593 = 31551702
163 + 31551539 = 31551702
199 + 31551503 = 31551702

Showing the first eight; more decompositions exist.
