Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8694440, here are decompositions:

43 + 8694397 = 8694440
61 + 8694379 = 8694440
109 + 8694331 = 8694440
127 + 8694313 = 8694440
193 + 8694247 = 8694440
199 + 8694241 = 8694440
229 + 8694211 = 8694440
331 + 8694109 = 8694440

Showing the first eight; more decompositions exist.
