Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631830, here are decompositions:

7 + 8631823 = 8631830
43 + 8631787 = 8631830
61 + 8631769 = 8631830
157 + 8631673 = 8631830
313 + 8631517 = 8631830
331 + 8631499 = 8631830
379 + 8631451 = 8631830
439 + 8631391 = 8631830

Showing the first eight; more decompositions exist.
