Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594862, here are decompositions:

163 + 31594699 = 31594862
181 + 31594681 = 31594862
283 + 31594579 = 31594862
373 + 31594489 = 31594862
433 + 31594429 = 31594862
463 + 31594399 = 31594862
823 + 31594039 = 31594862
919 + 31593943 = 31594862

Showing the first eight; more decompositions exist.
