Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600432, here are decompositions:

11 + 31600421 = 31600432
23 + 31600409 = 31600432
113 + 31600319 = 31600432
131 + 31600301 = 31600432
173 + 31600259 = 31600432
239 + 31600193 = 31600432
389 + 31600043 = 31600432
431 + 31600001 = 31600432

Showing the first eight; more decompositions exist.
