Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641432, here are decompositions:

3 + 8641429 = 8641432
11 + 8641421 = 8641432
71 + 8641361 = 8641432
83 + 8641349 = 8641432
101 + 8641331 = 8641432
113 + 8641319 = 8641432
131 + 8641301 = 8641432
353 + 8641079 = 8641432

Showing the first eight; more decompositions exist.
