Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459052, here are decompositions:

139 + 31458913 = 31459052
151 + 31458901 = 31459052
223 + 31458829 = 31459052
349 + 31458703 = 31459052
409 + 31458643 = 31459052
421 + 31458631 = 31459052
463 + 31458589 = 31459052
571 + 31458481 = 31459052

Showing the first eight; more decompositions exist.
