Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529050, here are decompositions:

53 + 31528997 = 31529050
83 + 31528967 = 31529050
197 + 31528853 = 31529050
227 + 31528823 = 31529050
239 + 31528811 = 31529050
353 + 31528697 = 31529050
491 + 31528559 = 31529050
503 + 31528547 = 31529050

Showing the first eight; more decompositions exist.
