Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620194, here are decompositions:

5 + 8620189 = 8620194
7 + 8620187 = 8620194
43 + 8620151 = 8620194
53 + 8620141 = 8620194
61 + 8620133 = 8620194
73 + 8620121 = 8620194
83 + 8620111 = 8620194
131 + 8620063 = 8620194

Showing the first eight; more decompositions exist.
