Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510432, here are decompositions:

29 + 31510403 = 31510432
113 + 31510319 = 31510432
263 + 31510169 = 31510432
293 + 31510139 = 31510432
311 + 31510121 = 31510432
353 + 31510079 = 31510432
431 + 31510001 = 31510432
461 + 31509971 = 31510432

Showing the first eight; more decompositions exist.
