Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45642, here are decompositions:
- 11 + 45631 = 45642
- 29 + 45613 = 45642
- 43 + 45599 = 45642
- 53 + 45589 = 45642
- 73 + 45569 = 45642
- 89 + 45553 = 45642
- 101 + 45541 = 45642
- 109 + 45533 = 45642
Showing the first eight; more decompositions exist.
