Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71678, here are decompositions:
- 7 + 71671 = 71678
- 31 + 71647 = 71678
- 109 + 71569 = 71678
- 127 + 71551 = 71678
- 151 + 71527 = 71678
- 199 + 71479 = 71678
- 241 + 71437 = 71678
- 331 + 71347 = 71678
Showing the first eight; more decompositions exist.
