Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11742, here are decompositions:
- 11 + 11731 = 11742
- 23 + 11719 = 11742
- 41 + 11701 = 11742
- 43 + 11699 = 11742
- 53 + 11689 = 11742
- 61 + 11681 = 11742
- 109 + 11633 = 11742
- 149 + 11593 = 11742
Showing the first eight; more decompositions exist.
