Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71760, here are decompositions:
- 19 + 71741 = 71760
- 41 + 71719 = 71760
- 47 + 71713 = 71760
- 53 + 71707 = 71760
- 61 + 71699 = 71760
- 67 + 71693 = 71760
- 89 + 71671 = 71760
- 97 + 71663 = 71760
Showing the first eight; more decompositions exist.
