Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612602, here are decompositions:

5 + 31612597 = 31612602
13 + 31612589 = 31612602
19 + 31612583 = 31612602
29 + 31612573 = 31612602
71 + 31612531 = 31612602
89 + 31612513 = 31612602
149 + 31612453 = 31612602
173 + 31612429 = 31612602

Showing the first eight; more decompositions exist.
