Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484468, here are decompositions:

7 + 31484461 = 31484468
19 + 31484449 = 31484468
109 + 31484359 = 31484468
151 + 31484317 = 31484468
229 + 31484239 = 31484468
307 + 31484161 = 31484468
397 + 31484071 = 31484468
409 + 31484059 = 31484468

Showing the first eight; more decompositions exist.
