Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624574, here are decompositions:

67 + 31624507 = 31624574
97 + 31624477 = 31624574
151 + 31624423 = 31624574
211 + 31624363 = 31624574
433 + 31624141 = 31624574
571 + 31624003 = 31624574
607 + 31623967 = 31624574
643 + 31623931 = 31624574

Showing the first eight; more decompositions exist.
