Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594472, here are decompositions:

43 + 31594429 = 31594472
73 + 31594399 = 31594472
79 + 31594393 = 31594472
139 + 31594333 = 31594472
163 + 31594309 = 31594472
199 + 31594273 = 31594472
313 + 31594159 = 31594472
409 + 31594063 = 31594472

Showing the first eight; more decompositions exist.
