Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563594, here are decompositions:

43 + 31563551 = 31563594
67 + 31563527 = 31563594
103 + 31563491 = 31563594
131 + 31563463 = 31563594
151 + 31563443 = 31563594
163 + 31563431 = 31563594
191 + 31563403 = 31563594
193 + 31563401 = 31563594

Showing the first eight; more decompositions exist.
