Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135690, here are decompositions:
- 19 + 135671 = 135690
- 29 + 135661 = 135690
- 41 + 135649 = 135690
- 43 + 135647 = 135690
- 53 + 135637 = 135690
- 67 + 135623 = 135690
- 73 + 135617 = 135690
- 83 + 135607 = 135690
Showing the first eight; more decompositions exist.
