Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155736, here are decompositions:
- 5 + 155731 = 155736
- 13 + 155723 = 155736
- 17 + 155719 = 155736
- 19 + 155717 = 155736
- 29 + 155707 = 155736
- 37 + 155699 = 155736
- 43 + 155693 = 155736
- 47 + 155689 = 155736
Showing the first eight; more decompositions exist.
