Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42544, here are decompositions:
- 11 + 42533 = 42544
- 53 + 42491 = 42544
- 71 + 42473 = 42544
- 83 + 42461 = 42544
- 101 + 42443 = 42544
- 107 + 42437 = 42544
- 137 + 42407 = 42544
- 251 + 42293 = 42544
Showing the first eight; more decompositions exist.
