Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530952, here are decompositions:

59 + 31530893 = 31530952
179 + 31530773 = 31530952
239 + 31530713 = 31530952
251 + 31530701 = 31530952
269 + 31530683 = 31530952
293 + 31530659 = 31530952
311 + 31530641 = 31530952
359 + 31530593 = 31530952

Showing the first eight; more decompositions exist.
