Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499682, here are decompositions:

23 + 31499659 = 31499682
61 + 31499621 = 31499682
83 + 31499599 = 31499682
89 + 31499593 = 31499682
191 + 31499491 = 31499682
223 + 31499459 = 31499682
251 + 31499431 = 31499682
271 + 31499411 = 31499682

Showing the first eight; more decompositions exist.
