Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618598, here are decompositions:

19 + 31618579 = 31618598
31 + 31618567 = 31618598
79 + 31618519 = 31618598
157 + 31618441 = 31618598
367 + 31618231 = 31618598
409 + 31618189 = 31618598
499 + 31618099 = 31618598
541 + 31618057 = 31618598

Showing the first eight; more decompositions exist.
