Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640430, here are decompositions:

3 + 8640427 = 8640430
11 + 8640419 = 8640430
23 + 8640407 = 8640430
101 + 8640329 = 8640430
167 + 8640263 = 8640430
179 + 8640251 = 8640430
233 + 8640197 = 8640430
269 + 8640161 = 8640430

Showing the first eight; more decompositions exist.
