Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645402, here are decompositions:

43 + 8645359 = 8645402
61 + 8645341 = 8645402
109 + 8645293 = 8645402
163 + 8645239 = 8645402
223 + 8645179 = 8645402
331 + 8645071 = 8645402
349 + 8645053 = 8645402
373 + 8645029 = 8645402

Showing the first eight; more decompositions exist.
