Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594502, here are decompositions:

13 + 31594489 = 31594502
73 + 31594429 = 31594502
103 + 31594399 = 31594502
109 + 31594393 = 31594502
151 + 31594351 = 31594502
193 + 31594309 = 31594502
229 + 31594273 = 31594502
421 + 31594081 = 31594502

Showing the first eight; more decompositions exist.
