Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496068, here are decompositions:

11 + 31496057 = 31496068
41 + 31496027 = 31496068
89 + 31495979 = 31496068
311 + 31495757 = 31496068
467 + 31495601 = 31496068
479 + 31495589 = 31496068
557 + 31495511 = 31496068
587 + 31495481 = 31496068

Showing the first eight; more decompositions exist.
