Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496228, here are decompositions:

7 + 31496221 = 31496228
19 + 31496209 = 31496228
67 + 31496161 = 31496228
109 + 31496119 = 31496228
307 + 31495921 = 31496228
331 + 31495897 = 31496228
349 + 31495879 = 31496228
409 + 31495819 = 31496228

Showing the first eight; more decompositions exist.
