Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678664, here are decompositions:
- 61 + 8678603 = 8678664
- 83 + 8678581 = 8678664
- 107 + 8678557 = 8678664
- 157 + 8678507 = 8678664
- 191 + 8678473 = 8678664
- 271 + 8678393 = 8678664
- 311 + 8678353 = 8678664
- 331 + 8678333 = 8678664
Showing the first eight; more decompositions exist.
