Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42450, here are decompositions:
- 7 + 42443 = 42450
- 13 + 42437 = 42450
- 17 + 42433 = 42450
- 41 + 42409 = 42450
- 43 + 42407 = 42450
- 47 + 42403 = 42450
- 53 + 42397 = 42450
- 59 + 42391 = 42450
Showing the first eight; more decompositions exist.
