Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678760, here are decompositions:
- 7 + 8678753 = 8678760
- 11 + 8678749 = 8678760
- 19 + 8678741 = 8678760
- 47 + 8678713 = 8678760
- 53 + 8678707 = 8678760
- 59 + 8678701 = 8678760
- 61 + 8678699 = 8678760
- 67 + 8678693 = 8678760
Showing the first eight; more decompositions exist.
