Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612670, here are decompositions:

3 + 31612667 = 31612670
7 + 31612663 = 31612670
43 + 31612627 = 31612670
73 + 31612597 = 31612670
97 + 31612573 = 31612670
139 + 31612531 = 31612670
157 + 31612513 = 31612670
241 + 31612429 = 31612670

Showing the first eight; more decompositions exist.
