Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592460, here are decompositions:

7 + 31592453 = 31592460
13 + 31592447 = 31592460
23 + 31592437 = 31592460
37 + 31592423 = 31592460
43 + 31592417 = 31592460
71 + 31592389 = 31592460
83 + 31592377 = 31592460
103 + 31592357 = 31592460

Showing the first eight; more decompositions exist.
