Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612492, here are decompositions:

5 + 31612487 = 31612492
11 + 31612481 = 31612492
101 + 31612391 = 31612492
179 + 31612313 = 31612492
251 + 31612241 = 31612492
269 + 31612223 = 31612492
293 + 31612199 = 31612492
383 + 31612109 = 31612492

Showing the first eight; more decompositions exist.
