Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499996, here are decompositions:

7 + 31499989 = 31499996
97 + 31499899 = 31499996
103 + 31499893 = 31499996
163 + 31499833 = 31499996
193 + 31499803 = 31499996
337 + 31499659 = 31499996
397 + 31499599 = 31499996
499 + 31499497 = 31499996

Showing the first eight; more decompositions exist.
