Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8635142, here are decompositions:

181 + 8634961 = 8635142
283 + 8634859 = 8635142
331 + 8634811 = 8635142
463 + 8634679 = 8635142
661 + 8634481 = 8635142
673 + 8634469 = 8635142
751 + 8634391 = 8635142
883 + 8634259 = 8635142

Showing the first eight; more decompositions exist.
