Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592844, here are decompositions:

11 + 31592833 = 31592844
47 + 31592797 = 31592844
71 + 31592773 = 31592844
83 + 31592761 = 31592844
97 + 31592747 = 31592844
167 + 31592677 = 31592844
181 + 31592663 = 31592844
193 + 31592651 = 31592844

Showing the first eight; more decompositions exist.
