Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592724, here are decompositions:

41 + 31592683 = 31592724
47 + 31592677 = 31592724
61 + 31592663 = 31592724
73 + 31592651 = 31592724
83 + 31592641 = 31592724
103 + 31592621 = 31592724
157 + 31592567 = 31592724
167 + 31592557 = 31592724

Showing the first eight; more decompositions exist.
