Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499466, here are decompositions:

7 + 31499459 = 31499466
59 + 31499407 = 31499466
67 + 31499399 = 31499466
79 + 31499387 = 31499466
83 + 31499383 = 31499466
137 + 31499329 = 31499466
139 + 31499327 = 31499466
157 + 31499309 = 31499466

Showing the first eight; more decompositions exist.
