Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592436, here are decompositions:

13 + 31592423 = 31592436
19 + 31592417 = 31592436
47 + 31592389 = 31592436
59 + 31592377 = 31592436
67 + 31592369 = 31592436
79 + 31592357 = 31592436
89 + 31592347 = 31592436
179 + 31592257 = 31592436

Showing the first eight; more decompositions exist.
