Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645044, here are decompositions:

53 + 8644991 = 8645044
131 + 8644913 = 8645044
263 + 8644781 = 8645044
293 + 8644751 = 8645044
383 + 8644661 = 8645044
491 + 8644553 = 8645044
587 + 8644457 = 8645044
593 + 8644451 = 8645044

Showing the first eight; more decompositions exist.
