Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489396, here are decompositions:

5 + 31489391 = 31489396
47 + 31489349 = 31489396
137 + 31489259 = 31489396
149 + 31489247 = 31489396
167 + 31489229 = 31489396
179 + 31489217 = 31489396
227 + 31489169 = 31489396
317 + 31489079 = 31489396

Showing the first eight; more decompositions exist.
