Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612354, here are decompositions:

3 + 31612351 = 31612354
41 + 31612313 = 31612354
47 + 31612307 = 31612354
113 + 31612241 = 31612354
131 + 31612223 = 31612354
233 + 31612121 = 31612354
311 + 31612043 = 31612354
443 + 31611911 = 31612354

Showing the first eight; more decompositions exist.
