Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489326, here are decompositions:

47 + 31489279 = 31489326
67 + 31489259 = 31489326
79 + 31489247 = 31489326
83 + 31489243 = 31489326
97 + 31489229 = 31489326
109 + 31489217 = 31489326
149 + 31489177 = 31489326
157 + 31489169 = 31489326

Showing the first eight; more decompositions exist.
