Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22742, here are decompositions:
- 3 + 22739 = 22742
- 43 + 22699 = 22742
- 73 + 22669 = 22742
- 103 + 22639 = 22742
- 193 + 22549 = 22742
- 199 + 22543 = 22742
- 211 + 22531 = 22742
- 241 + 22501 = 22742
Showing the first eight; more decompositions exist.
