Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582992, here are decompositions:

11 + 31582981 = 31582992
31 + 31582961 = 31582992
41 + 31582951 = 31582992
43 + 31582949 = 31582992
61 + 31582931 = 31582992
79 + 31582913 = 31582992
101 + 31582891 = 31582992
173 + 31582819 = 31582992

Showing the first eight; more decompositions exist.
