Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563762, here are decompositions:

29 + 31563733 = 31563762
79 + 31563683 = 31563762
193 + 31563569 = 31563762
211 + 31563551 = 31563762
271 + 31563491 = 31563762
311 + 31563451 = 31563762
331 + 31563431 = 31563762
359 + 31563403 = 31563762

Showing the first eight; more decompositions exist.
