Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136680, here are decompositions:
- 23 + 136657 = 136680
- 29 + 136651 = 136680
- 31 + 136649 = 136680
- 59 + 136621 = 136680
- 73 + 136607 = 136680
- 79 + 136601 = 136680
- 107 + 136573 = 136680
- 139 + 136541 = 136680
Showing the first eight; more decompositions exist.
