Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632040, here are decompositions:

13 + 8632027 = 8632040
31 + 8632009 = 8632040
37 + 8632003 = 8632040
61 + 8631979 = 8632040
97 + 8631943 = 8632040
271 + 8631769 = 8632040
367 + 8631673 = 8632040
523 + 8631517 = 8632040

Showing the first eight; more decompositions exist.
