Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500098, here are decompositions:

109 + 31499989 = 31500098
199 + 31499899 = 31500098
337 + 31499761 = 31500098
367 + 31499731 = 31500098
439 + 31499659 = 31500098
499 + 31499599 = 31500098
601 + 31499497 = 31500098
607 + 31499491 = 31500098

Showing the first eight; more decompositions exist.
