Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592070, here are decompositions:

17 + 31592053 = 31592070
19 + 31592051 = 31592070
23 + 31592047 = 31592070
31 + 31592039 = 31592070
71 + 31591999 = 31592070
73 + 31591997 = 31592070
113 + 31591957 = 31592070
157 + 31591913 = 31592070

Showing the first eight; more decompositions exist.
