Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560992, here are decompositions:

13 + 31560979 = 31560992
193 + 31560799 = 31560992
241 + 31560751 = 31560992
283 + 31560709 = 31560992
313 + 31560679 = 31560992
409 + 31560583 = 31560992
433 + 31560559 = 31560992
523 + 31560469 = 31560992

Showing the first eight; more decompositions exist.
