Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563892, here are decompositions:

11 + 31563881 = 31563892
29 + 31563863 = 31563892
401 + 31563491 = 31563892
449 + 31563443 = 31563892
461 + 31563431 = 31563892
491 + 31563401 = 31563892
683 + 31563209 = 31563892
743 + 31563149 = 31563892

Showing the first eight; more decompositions exist.
