Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661844, here are decompositions:

3 + 8661841 = 8661844
5 + 8661839 = 8661844
101 + 8661743 = 8661844
137 + 8661707 = 8661844
263 + 8661581 = 8661844
353 + 8661491 = 8661844
383 + 8661461 = 8661844
431 + 8661413 = 8661844

Showing the first eight; more decompositions exist.
