Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8610690, here are decompositions:

31 + 8610659 = 8610690
41 + 8610649 = 8610690
47 + 8610643 = 8610690
73 + 8610617 = 8610690
83 + 8610607 = 8610690
89 + 8610601 = 8610690
107 + 8610583 = 8610690
131 + 8610559 = 8610690

Showing the first eight; more decompositions exist.
