Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42444, here are decompositions:
- 7 + 42437 = 42444
- 11 + 42433 = 42444
- 37 + 42407 = 42444
- 41 + 42403 = 42444
- 47 + 42397 = 42444
- 53 + 42391 = 42444
- 71 + 42373 = 42444
- 107 + 42337 = 42444
Showing the first eight; more decompositions exist.
