Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484368, here are decompositions:

5 + 31484363 = 31484368
29 + 31484339 = 31484368
101 + 31484267 = 31484368
131 + 31484237 = 31484368
191 + 31484177 = 31484368
239 + 31484129 = 31484368
389 + 31483979 = 31484368
449 + 31483919 = 31484368

Showing the first eight; more decompositions exist.
