Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529088, here are decompositions:

7 + 31529081 = 31529088
179 + 31528909 = 31529088
257 + 31528831 = 31529088
277 + 31528811 = 31529088
281 + 31528807 = 31529088
337 + 31528751 = 31529088
347 + 31528741 = 31529088
359 + 31528729 = 31529088

Showing the first eight; more decompositions exist.
