Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484186, here are decompositions:

7 + 31484179 = 31484186
43 + 31484143 = 31484186
127 + 31484059 = 31484186
229 + 31483957 = 31484186
367 + 31483819 = 31484186
379 + 31483807 = 31484186
397 + 31483789 = 31484186
463 + 31483723 = 31484186

Showing the first eight; more decompositions exist.
