Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607626, here are decompositions:

47 + 31607579 = 31607626
137 + 31607489 = 31607626
179 + 31607447 = 31607626
227 + 31607399 = 31607626
263 + 31607363 = 31607626
269 + 31607357 = 31607626
317 + 31607309 = 31607626
389 + 31607237 = 31607626

Showing the first eight; more decompositions exist.
