Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608762, here are decompositions:

5 + 31608757 = 31608762
13 + 31608749 = 31608762
41 + 31608721 = 31608762
173 + 31608589 = 31608762
233 + 31608529 = 31608762
281 + 31608481 = 31608762
313 + 31608449 = 31608762
421 + 31608341 = 31608762

Showing the first eight; more decompositions exist.
