Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459610, here are decompositions:

211 + 31459399 = 31459610
223 + 31459387 = 31459610
271 + 31459339 = 31459610
349 + 31459261 = 31459610
409 + 31459201 = 31459610
487 + 31459123 = 31459610
499 + 31459111 = 31459610
541 + 31459069 = 31459610

Showing the first eight; more decompositions exist.
