Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594898, here are decompositions:

31 + 31594867 = 31594898
37 + 31594861 = 31594898
151 + 31594747 = 31594898
199 + 31594699 = 31594898
271 + 31594627 = 31594898
397 + 31594501 = 31594898
409 + 31594489 = 31594898
499 + 31594399 = 31594898

Showing the first eight; more decompositions exist.
