Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23042, here are decompositions:
- 3 + 23039 = 23042
- 13 + 23029 = 23042
- 31 + 23011 = 23042
- 79 + 22963 = 23042
- 181 + 22861 = 23042
- 373 + 22669 = 23042
- 421 + 22621 = 23042
- 499 + 22543 = 23042
Showing the first eight; more decompositions exist.
