Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459436, here are decompositions:

3 + 31459433 = 31459436
37 + 31459399 = 31459436
79 + 31459357 = 31459436
97 + 31459339 = 31459436
313 + 31459123 = 31459436
367 + 31459069 = 31459436
373 + 31459063 = 31459436
499 + 31458937 = 31459436

Showing the first eight; more decompositions exist.
