Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495068, here are decompositions:

5 + 31495063 = 31495068
89 + 31494979 = 31495068
131 + 31494937 = 31495068
149 + 31494919 = 31495068
181 + 31494887 = 31495068
251 + 31494817 = 31495068
331 + 31494737 = 31495068
347 + 31494721 = 31495068

Showing the first eight; more decompositions exist.
