Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677844, here are decompositions:

3 + 8677841 = 8677844
73 + 8677771 = 8677844
163 + 8677681 = 8677844
181 + 8677663 = 8677844
193 + 8677651 = 8677844
367 + 8677477 = 8677844
457 + 8677387 = 8677844
547 + 8677297 = 8677844

Showing the first eight; more decompositions exist.
