Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499484, here are decompositions:

17 + 31499467 = 31499484
53 + 31499431 = 31499484
73 + 31499411 = 31499484
83 + 31499401 = 31499484
97 + 31499387 = 31499484
101 + 31499383 = 31499484
113 + 31499371 = 31499484
157 + 31499327 = 31499484

Showing the first eight; more decompositions exist.
