Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563734, here are decompositions:

271 + 31563463 = 31563734
283 + 31563451 = 31563734
331 + 31563403 = 31563734
457 + 31563277 = 31563734
541 + 31563193 = 31563734
547 + 31563187 = 31563734
571 + 31563163 = 31563734
607 + 31563127 = 31563734

Showing the first eight; more decompositions exist.
