Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529548, here are decompositions:

41 + 31529507 = 31529548
101 + 31529447 = 31529548
227 + 31529321 = 31529548
269 + 31529279 = 31529548
461 + 31529087 = 31529548
467 + 31529081 = 31529548
797 + 31528751 = 31529548
1049 + 31528499 = 31529548

Showing the first eight; more decompositions exist.
