Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623098, here are decompositions:

37 + 31623061 = 31623098
139 + 31622959 = 31623098
151 + 31622947 = 31623098
457 + 31622641 = 31623098
499 + 31622599 = 31623098
607 + 31622491 = 31623098
631 + 31622467 = 31623098
709 + 31622389 = 31623098

Showing the first eight; more decompositions exist.
