Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563608, here are decompositions:

7 + 31563601 = 31563608
157 + 31563451 = 31563608
331 + 31563277 = 31563608
421 + 31563187 = 31563608
577 + 31563031 = 31563608
607 + 31563001 = 31563608
691 + 31562917 = 31563608
829 + 31562779 = 31563608

Showing the first eight; more decompositions exist.
