Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459406, here are decompositions:

7 + 31459399 = 31459406
19 + 31459387 = 31459406
67 + 31459339 = 31459406
283 + 31459123 = 31459406
313 + 31459093 = 31459406
337 + 31459069 = 31459406
439 + 31458967 = 31459406
499 + 31458907 = 31459406

Showing the first eight; more decompositions exist.
