Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640352, here are decompositions:

3 + 8640349 = 8640352
23 + 8640329 = 8640352
89 + 8640263 = 8640352
101 + 8640251 = 8640352
131 + 8640221 = 8640352
191 + 8640161 = 8640352
293 + 8640059 = 8640352
401 + 8639951 = 8640352

Showing the first eight; more decompositions exist.
