Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459364, here are decompositions:

7 + 31459357 = 31459364
43 + 31459321 = 31459364
73 + 31459291 = 31459364
103 + 31459261 = 31459364
163 + 31459201 = 31459364
241 + 31459123 = 31459364
271 + 31459093 = 31459364
397 + 31458967 = 31459364

Showing the first eight; more decompositions exist.
