Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499762, here are decompositions:

31 + 31499731 = 31499762
103 + 31499659 = 31499762
163 + 31499599 = 31499762
271 + 31499491 = 31499762
331 + 31499431 = 31499762
379 + 31499383 = 31499762
421 + 31499341 = 31499762
433 + 31499329 = 31499762

Showing the first eight; more decompositions exist.
