Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559088, here are decompositions:

7 + 31559081 = 31559088
17 + 31559071 = 31559088
19 + 31559069 = 31559088
37 + 31559051 = 31559088
61 + 31559027 = 31559088
131 + 31558957 = 31559088
149 + 31558939 = 31559088
191 + 31558897 = 31559088

Showing the first eight; more decompositions exist.
