Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620068, here are decompositions:

31 + 31620037 = 31620068
79 + 31619989 = 31620068
157 + 31619911 = 31620068
199 + 31619869 = 31620068
307 + 31619761 = 31620068
421 + 31619647 = 31620068
457 + 31619611 = 31620068
541 + 31619527 = 31620068

Showing the first eight; more decompositions exist.
