Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483388, here are decompositions:

19 + 31483369 = 31483388
37 + 31483351 = 31483388
61 + 31483327 = 31483388
127 + 31483261 = 31483388
151 + 31483237 = 31483388
271 + 31483117 = 31483388
337 + 31483051 = 31483388
397 + 31482991 = 31483388

Showing the first eight; more decompositions exist.
