Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155758, here are decompositions:
- 11 + 155747 = 155758
- 17 + 155741 = 155758
- 41 + 155717 = 155758
- 59 + 155699 = 155758
- 101 + 155657 = 155758
- 131 + 155627 = 155758
- 137 + 155621 = 155758
- 149 + 155609 = 155758
Showing the first eight; more decompositions exist.
