Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529608, here are decompositions:

41 + 31529567 = 31529608
101 + 31529507 = 31529608
137 + 31529471 = 31529608
359 + 31529249 = 31529608
389 + 31529219 = 31529608
521 + 31529087 = 31529608
641 + 31528967 = 31529608
797 + 31528811 = 31529608

Showing the first eight; more decompositions exist.
