Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749926, here are decompositions:

5 + 8749921 = 8749926
23 + 8749903 = 8749926
79 + 8749847 = 8749926
89 + 8749837 = 8749926
109 + 8749817 = 8749926
113 + 8749813 = 8749926
137 + 8749789 = 8749926
139 + 8749787 = 8749926

Showing the first eight; more decompositions exist.
