Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484434, here are decompositions:

17 + 31484417 = 31484434
71 + 31484363 = 31484434
131 + 31484303 = 31484434
167 + 31484267 = 31484434
197 + 31484237 = 31484434
227 + 31484207 = 31484434
257 + 31484177 = 31484434
353 + 31484081 = 31484434

Showing the first eight; more decompositions exist.
