Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612372, here are decompositions:

3 + 31612369 = 31612372
59 + 31612313 = 31612372
131 + 31612241 = 31612372
149 + 31612223 = 31612372
173 + 31612199 = 31612372
251 + 31612121 = 31612372
263 + 31612109 = 31612372
293 + 31612079 = 31612372

Showing the first eight; more decompositions exist.
