Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459038, here are decompositions:

7 + 31459031 = 31459038
19 + 31459019 = 31459038
71 + 31458967 = 31459038
101 + 31458937 = 31459038
131 + 31458907 = 31459038
137 + 31458901 = 31459038
239 + 31458799 = 31459038
241 + 31458797 = 31459038

Showing the first eight; more decompositions exist.
