Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582792, here are decompositions:

11 + 31582781 = 31582792
53 + 31582739 = 31582792
113 + 31582679 = 31582792
179 + 31582613 = 31582792
191 + 31582601 = 31582792
233 + 31582559 = 31582792
239 + 31582553 = 31582792
383 + 31582409 = 31582792

Showing the first eight; more decompositions exist.
