Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532088, here are decompositions:

17 + 31532071 = 31532088
67 + 31532021 = 31532088
157 + 31531931 = 31532088
167 + 31531921 = 31532088
179 + 31531909 = 31532088
271 + 31531817 = 31532088
337 + 31531751 = 31532088
409 + 31531679 = 31532088

Showing the first eight; more decompositions exist.
