Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45150, here are decompositions:
- 11 + 45139 = 45150
- 13 + 45137 = 45150
- 19 + 45131 = 45150
- 23 + 45127 = 45150
- 29 + 45121 = 45150
- 31 + 45119 = 45150
- 67 + 45083 = 45150
- 73 + 45077 = 45150
Showing the first eight; more decompositions exist.
