Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519606, here are decompositions:

5 + 31519601 = 31519606
23 + 31519583 = 31519606
149 + 31519457 = 31519606
179 + 31519427 = 31519606
227 + 31519379 = 31519606
317 + 31519289 = 31519606
353 + 31519253 = 31519606
359 + 31519247 = 31519606

Showing the first eight; more decompositions exist.
