Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641954, here are decompositions:

5 + 8641949 = 8641954
71 + 8641883 = 8641954
137 + 8641817 = 8641954
173 + 8641781 = 8641954
257 + 8641697 = 8641954
281 + 8641673 = 8641954
311 + 8641643 = 8641954
383 + 8641571 = 8641954

Showing the first eight; more decompositions exist.
