Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482806, here are decompositions:

7 + 31482799 = 31482806
97 + 31482709 = 31482806
139 + 31482667 = 31482806
163 + 31482643 = 31482806
193 + 31482613 = 31482806
307 + 31482499 = 31482806
367 + 31482439 = 31482806
379 + 31482427 = 31482806

Showing the first eight; more decompositions exist.
