Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8652578, here are decompositions:

7 + 8652571 = 8652578
229 + 8652349 = 8652578
349 + 8652229 = 8652578
367 + 8652211 = 8652578
439 + 8652139 = 8652578
499 + 8652079 = 8652578
541 + 8652037 = 8652578
601 + 8651977 = 8652578

Showing the first eight; more decompositions exist.
