Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8694220, here are decompositions:

23 + 8694197 = 8694220
89 + 8694131 = 8694220
137 + 8694083 = 8694220
173 + 8694047 = 8694220
251 + 8693969 = 8694220
263 + 8693957 = 8694220
383 + 8693837 = 8694220
419 + 8693801 = 8694220

Showing the first eight; more decompositions exist.
