Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582712, here are decompositions:

79 + 31582633 = 31582712
103 + 31582609 = 31582712
181 + 31582531 = 31582712
199 + 31582513 = 31582712
223 + 31582489 = 31582712
241 + 31582471 = 31582712
313 + 31582399 = 31582712
379 + 31582333 = 31582712

Showing the first eight; more decompositions exist.
