Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496212, here are decompositions:

3 + 31496209 = 31496212
71 + 31496141 = 31496212
89 + 31496123 = 31496212
113 + 31496099 = 31496212
233 + 31495979 = 31496212
263 + 31495949 = 31496212
353 + 31495859 = 31496212
479 + 31495733 = 31496212

Showing the first eight; more decompositions exist.
