Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500332, here are decompositions:

139 + 31500193 = 31500332
433 + 31499899 = 31500332
439 + 31499893 = 31500332
499 + 31499833 = 31500332
571 + 31499761 = 31500332
601 + 31499731 = 31500332
673 + 31499659 = 31500332
733 + 31499599 = 31500332

Showing the first eight; more decompositions exist.
