Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484072, here are decompositions:

3 + 31484069 = 31484072
13 + 31484059 = 31484072
211 + 31483861 = 31484072
271 + 31483801 = 31484072
283 + 31483789 = 31484072
313 + 31483759 = 31484072
349 + 31483723 = 31484072
409 + 31483663 = 31484072

Showing the first eight; more decompositions exist.
