Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612426, here are decompositions:

3 + 31612423 = 31612426
113 + 31612313 = 31612426
149 + 31612277 = 31612426
227 + 31612199 = 31612426
317 + 31612109 = 31612426
347 + 31612079 = 31612426
383 + 31612043 = 31612426
509 + 31611917 = 31612426

Showing the first eight; more decompositions exist.
