Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744840, here are decompositions:

3 + 8744837 = 8744840
7 + 8744833 = 8744840
103 + 8744737 = 8744840
157 + 8744683 = 8744840
229 + 8744611 = 8744840
241 + 8744599 = 8744840
277 + 8744563 = 8744840
283 + 8744557 = 8744840

Showing the first eight; more decompositions exist.
