Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744736, here are decompositions:
- 19 + 8744717 = 8744736
- 29 + 8744707 = 8744736
- 53 + 8744683 = 8744736
- 73 + 8744663 = 8744736
- 109 + 8744627 = 8744736
- 137 + 8744599 = 8744736
- 173 + 8744563 = 8744736
- 179 + 8744557 = 8744736
Showing the first eight; more decompositions exist.
