Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45648, here are decompositions:
- 7 + 45641 = 45648
- 17 + 45631 = 45648
- 59 + 45589 = 45648
- 61 + 45587 = 45648
- 79 + 45569 = 45648
- 107 + 45541 = 45648
- 151 + 45497 = 45648
- 157 + 45491 = 45648
Showing the first eight; more decompositions exist.
