Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621194, here are decompositions:

5 + 8621189 = 8621194
11 + 8621183 = 8621194
41 + 8621153 = 8621194
47 + 8621147 = 8621194
107 + 8621087 = 8621194
251 + 8620943 = 8621194
347 + 8620847 = 8621194
353 + 8620841 = 8621194

Showing the first eight; more decompositions exist.
