Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592446, here are decompositions:

23 + 31592423 = 31592446
29 + 31592417 = 31592446
89 + 31592357 = 31592446
227 + 31592219 = 31592446
233 + 31592213 = 31592446
317 + 31592129 = 31592446
449 + 31591997 = 31592446
467 + 31591979 = 31592446

Showing the first eight; more decompositions exist.
