Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495038, here are decompositions:

19 + 31495019 = 31495038
59 + 31494979 = 31495038
89 + 31494949 = 31495038
101 + 31494937 = 31495038
131 + 31494907 = 31495038
151 + 31494887 = 31495038
229 + 31494809 = 31495038
257 + 31494781 = 31495038

Showing the first eight; more decompositions exist.
