Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619164, here are decompositions:

7 + 8619157 = 8619164
13 + 8619151 = 8619164
67 + 8619097 = 8619164
97 + 8619067 = 8619164
241 + 8618923 = 8619164
271 + 8618893 = 8619164
313 + 8618851 = 8619164
331 + 8618833 = 8619164

Showing the first eight; more decompositions exist.
