Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528194, here are decompositions:

23 + 31528171 = 31528194
37 + 31528157 = 31528194
43 + 31528151 = 31528194
67 + 31528127 = 31528194
73 + 31528121 = 31528194
83 + 31528111 = 31528194
101 + 31528093 = 31528194
127 + 31528067 = 31528194

Showing the first eight; more decompositions exist.
