Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484228, here are decompositions:

19 + 31484209 = 31484228
67 + 31484161 = 31484228
157 + 31484071 = 31484228
271 + 31483957 = 31484228
367 + 31483861 = 31484228
409 + 31483819 = 31484228
421 + 31483807 = 31484228
439 + 31483789 = 31484228

Showing the first eight; more decompositions exist.
