Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459004, here are decompositions:

37 + 31458967 = 31459004
67 + 31458937 = 31459004
97 + 31458907 = 31459004
103 + 31458901 = 31459004
307 + 31458697 = 31459004
337 + 31458667 = 31459004
373 + 31458631 = 31459004
397 + 31458607 = 31459004

Showing the first eight; more decompositions exist.
