Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744730, here are decompositions:

13 + 8744717 = 8744730
19 + 8744711 = 8744730
23 + 8744707 = 8744730
47 + 8744683 = 8744730
67 + 8744663 = 8744730
103 + 8744627 = 8744730
131 + 8744599 = 8744730
167 + 8744563 = 8744730

Showing the first eight; more decompositions exist.
