Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155764, here are decompositions:
- 17 + 155747 = 155764
- 23 + 155741 = 155764
- 41 + 155723 = 155764
- 47 + 155717 = 155764
- 71 + 155693 = 155764
- 101 + 155663 = 155764
- 107 + 155657 = 155764
- 137 + 155627 = 155764
Showing the first eight; more decompositions exist.
