Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499562, here are decompositions:

71 + 31499491 = 31499562
103 + 31499459 = 31499562
131 + 31499431 = 31499562
151 + 31499411 = 31499562
163 + 31499399 = 31499562
179 + 31499383 = 31499562
191 + 31499371 = 31499562
233 + 31499329 = 31499562

Showing the first eight; more decompositions exist.
