Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592760, here are decompositions:

13 + 31592747 = 31592760
83 + 31592677 = 31592760
97 + 31592663 = 31592760
109 + 31592651 = 31592760
139 + 31592621 = 31592760
193 + 31592567 = 31592760
229 + 31592531 = 31592760
271 + 31592489 = 31592760

Showing the first eight; more decompositions exist.
