Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496038, here are decompositions:

11 + 31496027 = 31496038
59 + 31495979 = 31496038
89 + 31495949 = 31496038
179 + 31495859 = 31496038
191 + 31495847 = 31496038
281 + 31495757 = 31496038
347 + 31495691 = 31496038
449 + 31495589 = 31496038

Showing the first eight; more decompositions exist.
