Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612754, here are decompositions:

7 + 31612747 = 31612754
127 + 31612627 = 31612754
157 + 31612597 = 31612754
181 + 31612573 = 31612754
223 + 31612531 = 31612754
241 + 31612513 = 31612754
331 + 31612423 = 31612754
373 + 31612381 = 31612754

Showing the first eight; more decompositions exist.
