Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500092, here are decompositions:

103 + 31499989 = 31500092
193 + 31499899 = 31500092
199 + 31499893 = 31500092
229 + 31499863 = 31500092
331 + 31499761 = 31500092
433 + 31499659 = 31500092
499 + 31499593 = 31500092
601 + 31499491 = 31500092

Showing the first eight; more decompositions exist.
