Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487822, here are decompositions:

3 + 487819 = 487822
11 + 487811 = 487822
29 + 487793 = 487822
53 + 487769 = 487822
89 + 487733 = 487822
113 + 487709 = 487822
131 + 487691 = 487822
173 + 487649 = 487822

Showing the first eight; more decompositions exist.
