Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71772, here are decompositions:
- 11 + 71761 = 71772
- 31 + 71741 = 71772
- 53 + 71719 = 71772
- 59 + 71713 = 71772
- 61 + 71711 = 71772
- 73 + 71699 = 71772
- 79 + 71693 = 71772
- 101 + 71671 = 71772
Showing the first eight; more decompositions exist.
