Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459600, here are decompositions:

47 + 31459553 = 31459600
59 + 31459541 = 31459600
83 + 31459517 = 31459600
101 + 31459499 = 31459600
113 + 31459487 = 31459600
167 + 31459433 = 31459600
191 + 31459409 = 31459600
251 + 31459349 = 31459600

Showing the first eight; more decompositions exist.
