Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484672, here are decompositions:

103 + 31484569 = 31484672
139 + 31484533 = 31484672
211 + 31484461 = 31484672
223 + 31484449 = 31484672
313 + 31484359 = 31484672
433 + 31484239 = 31484672
463 + 31484209 = 31484672
601 + 31484071 = 31484672

Showing the first eight; more decompositions exist.
