Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45750, here are decompositions:
- 13 + 45737 = 45750
- 43 + 45707 = 45750
- 53 + 45697 = 45750
- 59 + 45691 = 45750
- 73 + 45677 = 45750
- 83 + 45667 = 45750
- 109 + 45641 = 45750
- 137 + 45613 = 45750
Showing the first eight; more decompositions exist.
