Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563602, here are decompositions:

139 + 31563463 = 31563602
151 + 31563451 = 31563602
199 + 31563403 = 31563602
211 + 31563391 = 31563602
349 + 31563253 = 31563602
409 + 31563193 = 31563602
439 + 31563163 = 31563602
571 + 31563031 = 31563602

Showing the first eight; more decompositions exist.
