Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67688, here are decompositions:
- 37 + 67651 = 67688
- 109 + 67579 = 67688
- 151 + 67537 = 67688
- 157 + 67531 = 67688
- 199 + 67489 = 67688
- 211 + 67477 = 67688
- 241 + 67447 = 67688
- 277 + 67411 = 67688
Showing the first eight; more decompositions exist.
