Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155716, here are decompositions:
- 17 + 155699 = 155716
- 23 + 155693 = 155716
- 53 + 155663 = 155716
- 59 + 155657 = 155716
- 89 + 155627 = 155716
- 107 + 155609 = 155716
- 137 + 155579 = 155716
- 179 + 155537 = 155716
Showing the first eight; more decompositions exist.
