Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641544, here are decompositions:

3 + 8641541 = 8641544
31 + 8641513 = 8641544
73 + 8641471 = 8641544
193 + 8641351 = 8641544
271 + 8641273 = 8641544
313 + 8641231 = 8641544
397 + 8641147 = 8641544
577 + 8640967 = 8641544

Showing the first eight; more decompositions exist.
