Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618190, here are decompositions:

17 + 8618173 = 8618190
41 + 8618149 = 8618190
43 + 8618147 = 8618190
59 + 8618131 = 8618190
71 + 8618119 = 8618190
83 + 8618107 = 8618190
101 + 8618089 = 8618190
103 + 8618087 = 8618190

Showing the first eight; more decompositions exist.
