Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691044, here are decompositions:

73 + 8690971 = 8691044
97 + 8690947 = 8691044
127 + 8690917 = 8691044
223 + 8690821 = 8691044
277 + 8690767 = 8691044
331 + 8690713 = 8691044
367 + 8690677 = 8691044
433 + 8690611 = 8691044

Showing the first eight; more decompositions exist.
