Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612498, here are decompositions:

11 + 31612487 = 31612498
17 + 31612481 = 31612498
107 + 31612391 = 31612498
191 + 31612307 = 31612498
257 + 31612241 = 31612498
347 + 31612151 = 31612498
389 + 31612109 = 31612498
419 + 31612079 = 31612498

Showing the first eight; more decompositions exist.
