Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529098, here are decompositions:

11 + 31529087 = 31529098
17 + 31529081 = 31529098
101 + 31528997 = 31529098
131 + 31528967 = 31529098
257 + 31528841 = 31529098
347 + 31528751 = 31529098
401 + 31528697 = 31529098
599 + 31528499 = 31529098

Showing the first eight; more decompositions exist.
