Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460158, here are decompositions:

29 + 31460129 = 31460158
227 + 31459931 = 31460158
311 + 31459847 = 31460158
449 + 31459709 = 31460158
461 + 31459697 = 31460158
479 + 31459679 = 31460158
491 + 31459667 = 31460158
617 + 31459541 = 31460158

Showing the first eight; more decompositions exist.
