Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672784, here are decompositions:
- 5 + 8672779 = 8672784
- 11 + 8672773 = 8672784
- 17 + 8672767 = 8672784
- 53 + 8672731 = 8672784
- 61 + 8672723 = 8672784
- 97 + 8672687 = 8672784
- 137 + 8672647 = 8672784
- 163 + 8672621 = 8672784
Showing the first eight; more decompositions exist.
