Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612226, here are decompositions:

3 + 31612223 = 31612226
157 + 31612069 = 31612226
229 + 31611997 = 31612226
397 + 31611829 = 31612226
409 + 31611817 = 31612226
523 + 31611703 = 31612226
619 + 31611607 = 31612226
643 + 31611583 = 31612226

Showing the first eight; more decompositions exist.
