Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484338, here are decompositions:

71 + 31484267 = 31484338
101 + 31484237 = 31484338
131 + 31484207 = 31484338
257 + 31484081 = 31484338
269 + 31484069 = 31484338
359 + 31483979 = 31484338
419 + 31483919 = 31484338
449 + 31483889 = 31484338

Showing the first eight; more decompositions exist.
