Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619822, here are decompositions:

61 + 31619761 = 31619822
109 + 31619713 = 31619822
139 + 31619683 = 31619822
211 + 31619611 = 31619822
313 + 31619509 = 31619822
433 + 31619389 = 31619822
463 + 31619359 = 31619822
541 + 31619281 = 31619822

Showing the first eight; more decompositions exist.
