Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649846, here are decompositions:

43 + 8649803 = 8649846
53 + 8649793 = 8649846
83 + 8649763 = 8649846
89 + 8649757 = 8649846
157 + 8649689 = 8649846
223 + 8649623 = 8649846
313 + 8649533 = 8649846
367 + 8649479 = 8649846

Showing the first eight; more decompositions exist.
