Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484538, here are decompositions:

5 + 31484533 = 31484538
89 + 31484449 = 31484538
179 + 31484359 = 31484538
199 + 31484339 = 31484538
257 + 31484281 = 31484538
271 + 31484267 = 31484538
331 + 31484207 = 31484538
359 + 31484179 = 31484538

Showing the first eight; more decompositions exist.
