Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31561414, here are decompositions:

11 + 31561403 = 31561414
23 + 31561391 = 31561414
41 + 31561373 = 31561414
113 + 31561301 = 31561414
167 + 31561247 = 31561414
173 + 31561241 = 31561414
293 + 31561121 = 31561414
347 + 31561067 = 31561414

Showing the first eight; more decompositions exist.
