Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588832, here are decompositions:

19 + 31588813 = 31588832
139 + 31588693 = 31588832
229 + 31588603 = 31588832
271 + 31588561 = 31588832
349 + 31588483 = 31588832
433 + 31588399 = 31588832
463 + 31588369 = 31588832
631 + 31588201 = 31588832

Showing the first eight; more decompositions exist.
