Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690444, here are decompositions:

31 + 8690413 = 8690444
67 + 8690377 = 8690444
73 + 8690371 = 8690444
127 + 8690317 = 8690444
151 + 8690293 = 8690444
223 + 8690221 = 8690444
241 + 8690203 = 8690444
271 + 8690173 = 8690444

Showing the first eight; more decompositions exist.
