Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640292, here are decompositions:

5 + 8640287 = 8640292
29 + 8640263 = 8640292
41 + 8640251 = 8640292
71 + 8640221 = 8640292
131 + 8640161 = 8640292
233 + 8640059 = 8640292
383 + 8639909 = 8640292
389 + 8639903 = 8640292

Showing the first eight; more decompositions exist.
