Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612600, here are decompositions:

3 + 31612597 = 31612600
11 + 31612589 = 31612600
17 + 31612583 = 31612600
53 + 31612547 = 31612600
113 + 31612487 = 31612600
293 + 31612307 = 31612600
359 + 31612241 = 31612600
401 + 31612199 = 31612600

Showing the first eight; more decompositions exist.
