Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738784, here are decompositions:
- 17 + 8738767 = 8738784
- 71 + 8738713 = 8738784
- 73 + 8738711 = 8738784
- 113 + 8738671 = 8738784
- 193 + 8738591 = 8738784
- 251 + 8738533 = 8738784
- 277 + 8738507 = 8738784
- 293 + 8738491 = 8738784
Showing the first eight; more decompositions exist.
