Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632438, here are decompositions:

47 + 8632391 = 8632438
71 + 8632367 = 8632438
251 + 8632187 = 8632438
281 + 8632157 = 8632438
461 + 8631977 = 8632438
557 + 8631881 = 8632438
587 + 8631851 = 8632438
701 + 8631737 = 8632438

Showing the first eight; more decompositions exist.
