Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749946, here are decompositions:

19 + 8749927 = 8749946
43 + 8749903 = 8749946
109 + 8749837 = 8749946
157 + 8749789 = 8749946
193 + 8749753 = 8749946
277 + 8749669 = 8749946
367 + 8749579 = 8749946
397 + 8749549 = 8749946

Showing the first eight; more decompositions exist.
