Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608588, here are decompositions:

59 + 31608529 = 31608588
61 + 31608527 = 31608588
107 + 31608481 = 31608588
139 + 31608449 = 31608588
239 + 31608349 = 31608588
251 + 31608337 = 31608588
269 + 31608319 = 31608588
317 + 31608271 = 31608588

Showing the first eight; more decompositions exist.
