Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612330, here are decompositions:

17 + 31612313 = 31612330
23 + 31612307 = 31612330
53 + 31612277 = 31612330
89 + 31612241 = 31612330
107 + 31612223 = 31612330
131 + 31612199 = 31612330
179 + 31612151 = 31612330
251 + 31612079 = 31612330

Showing the first eight; more decompositions exist.
