Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79140, here are decompositions:
- 7 + 79133 = 79140
- 29 + 79111 = 79140
- 37 + 79103 = 79140
- 53 + 79087 = 79140
- 97 + 79043 = 79140
- 101 + 79039 = 79140
- 109 + 79031 = 79140
- 151 + 78989 = 79140
Showing the first eight; more decompositions exist.
