Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612698, here are decompositions:

31 + 31612667 = 31612698
37 + 31612661 = 31612698
71 + 31612627 = 31612698
79 + 31612619 = 31612698
101 + 31612597 = 31612698
109 + 31612589 = 31612698
151 + 31612547 = 31612698
167 + 31612531 = 31612698

Showing the first eight; more decompositions exist.
