Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459434, here are decompositions:

47 + 31459387 = 31459434
113 + 31459321 = 31459434
173 + 31459261 = 31459434
211 + 31459223 = 31459434
233 + 31459201 = 31459434
283 + 31459151 = 31459434
311 + 31459123 = 31459434
467 + 31458967 = 31459434

Showing the first eight; more decompositions exist.
