Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756430, here are decompositions:

17 + 8756413 = 8756430
29 + 8756401 = 8756430
37 + 8756393 = 8756430
73 + 8756357 = 8756430
97 + 8756333 = 8756430
107 + 8756323 = 8756430
113 + 8756317 = 8756430
131 + 8756299 = 8756430

Showing the first eight; more decompositions exist.
