Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73180, here are decompositions:
- 47 + 73133 = 73180
- 53 + 73127 = 73180
- 59 + 73121 = 73180
- 89 + 73091 = 73180
- 101 + 73079 = 73180
- 137 + 73043 = 73180
- 167 + 73013 = 73180
- 227 + 72953 = 73180
Showing the first eight; more decompositions exist.
