Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618194, here are decompositions:

47 + 8618147 = 8618194
107 + 8618087 = 8618194
131 + 8618063 = 8618194
173 + 8618021 = 8618194
251 + 8617943 = 8618194
317 + 8617877 = 8618194
491 + 8617703 = 8618194
647 + 8617547 = 8618194

Showing the first eight; more decompositions exist.
