Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482822, here are decompositions:

23 + 31482799 = 31482822
43 + 31482779 = 31482822
61 + 31482761 = 31482822
79 + 31482743 = 31482822
113 + 31482709 = 31482822
139 + 31482683 = 31482822
179 + 31482643 = 31482822
181 + 31482641 = 31482822

Showing the first eight; more decompositions exist.
