Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71748, here are decompositions:
- 7 + 71741 = 71748
- 29 + 71719 = 71748
- 37 + 71711 = 71748
- 41 + 71707 = 71748
- 101 + 71647 = 71748
- 151 + 71597 = 71748
- 179 + 71569 = 71748
- 197 + 71551 = 71748
Showing the first eight; more decompositions exist.
