Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499462, here are decompositions:

3 + 31499459 = 31499462
31 + 31499431 = 31499462
61 + 31499401 = 31499462
79 + 31499383 = 31499462
139 + 31499323 = 31499462
151 + 31499311 = 31499462
223 + 31499239 = 31499462
439 + 31499023 = 31499462

Showing the first eight; more decompositions exist.
