Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79170, here are decompositions:
- 11 + 79159 = 79170
- 17 + 79153 = 79170
- 19 + 79151 = 79170
- 23 + 79147 = 79170
- 31 + 79139 = 79170
- 37 + 79133 = 79170
- 59 + 79111 = 79170
- 67 + 79103 = 79170
Showing the first eight; more decompositions exist.
