Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592430, here are decompositions:

7 + 31592423 = 31592430
13 + 31592417 = 31592430
19 + 31592411 = 31592430
41 + 31592389 = 31592430
53 + 31592377 = 31592430
61 + 31592369 = 31592430
73 + 31592357 = 31592430
83 + 31592347 = 31592430

Showing the first eight; more decompositions exist.
