Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459192, here are decompositions:

41 + 31459151 = 31459192
59 + 31459133 = 31459192
173 + 31459019 = 31459192
239 + 31458953 = 31459192
269 + 31458923 = 31459192
431 + 31458761 = 31459192
491 + 31458701 = 31459192
503 + 31458689 = 31459192

Showing the first eight; more decompositions exist.
