Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496076, here are decompositions:

19 + 31496057 = 31496076
97 + 31495979 = 31496076
127 + 31495949 = 31496076
179 + 31495897 = 31496076
197 + 31495879 = 31496076
229 + 31495847 = 31496076
257 + 31495819 = 31496076
347 + 31495729 = 31496076

Showing the first eight; more decompositions exist.
