Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592790, here are decompositions:

11 + 31592779 = 31592790
17 + 31592773 = 31592790
29 + 31592761 = 31592790
43 + 31592747 = 31592790
107 + 31592683 = 31592790
113 + 31592677 = 31592790
127 + 31592663 = 31592790
139 + 31592651 = 31592790

Showing the first eight; more decompositions exist.
