Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620662, here are decompositions:

61 + 31620601 = 31620662
163 + 31620499 = 31620662
181 + 31620481 = 31620662
433 + 31620229 = 31620662
439 + 31620223 = 31620662
523 + 31620139 = 31620662
643 + 31620019 = 31620662
673 + 31619989 = 31620662

Showing the first eight; more decompositions exist.
