Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534924, here are decompositions:

11 + 31534913 = 31534924
53 + 31534871 = 31534924
137 + 31534787 = 31534924
167 + 31534757 = 31534924
173 + 31534751 = 31534924
233 + 31534691 = 31534924
293 + 31534631 = 31534924
431 + 31534493 = 31534924

Showing the first eight; more decompositions exist.
