Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450598, here are decompositions:

19 + 31450579 = 31450598
211 + 31450387 = 31450598
229 + 31450369 = 31450598
307 + 31450291 = 31450598
379 + 31450219 = 31450598
457 + 31450141 = 31450598
499 + 31450099 = 31450598
541 + 31450057 = 31450598

Showing the first eight; more decompositions exist.
