Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71730, here are decompositions:
- 11 + 71719 = 71730
- 17 + 71713 = 71730
- 19 + 71711 = 71730
- 23 + 71707 = 71730
- 31 + 71699 = 71730
- 37 + 71693 = 71730
- 59 + 71671 = 71730
- 67 + 71663 = 71730
Showing the first eight; more decompositions exist.
