Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594448, here are decompositions:

19 + 31594429 = 31594448
97 + 31594351 = 31594448
139 + 31594309 = 31594448
211 + 31594237 = 31594448
367 + 31594081 = 31594448
409 + 31594039 = 31594448
547 + 31593901 = 31594448
661 + 31593787 = 31594448

Showing the first eight; more decompositions exist.
