Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744818, here are decompositions:

101 + 8744717 = 8744818
107 + 8744711 = 8744818
191 + 8744627 = 8744818
281 + 8744537 = 8744818
311 + 8744507 = 8744818
359 + 8744459 = 8744818
521 + 8744297 = 8744818
557 + 8744261 = 8744818

Showing the first eight; more decompositions exist.
