Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582592, here are decompositions:

3 + 31582589 = 31582592
61 + 31582531 = 31582592
79 + 31582513 = 31582592
103 + 31582489 = 31582592
193 + 31582399 = 31582592
271 + 31582321 = 31582592
409 + 31582183 = 31582592
421 + 31582171 = 31582592

Showing the first eight; more decompositions exist.
