Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459532, here are decompositions:

193 + 31459339 = 31459532
211 + 31459321 = 31459532
241 + 31459291 = 31459532
271 + 31459261 = 31459532
331 + 31459201 = 31459532
409 + 31459123 = 31459532
421 + 31459111 = 31459532
439 + 31459093 = 31459532

Showing the first eight; more decompositions exist.
