Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582122, here are decompositions:

29 + 31582093 = 31582122
73 + 31582049 = 31582122
79 + 31582043 = 31582122
101 + 31582021 = 31582122
139 + 31581983 = 31582122
149 + 31581973 = 31582122
211 + 31581911 = 31582122
233 + 31581889 = 31582122

Showing the first eight; more decompositions exist.
