Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641364, here are decompositions:

3 + 8641361 = 8641364
13 + 8641351 = 8641364
37 + 8641327 = 8641364
271 + 8641093 = 8641364
397 + 8640967 = 8641364
541 + 8640823 = 8641364
547 + 8640817 = 8641364
577 + 8640787 = 8641364

Showing the first eight; more decompositions exist.
