Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45168, here are decompositions:
- 7 + 45161 = 45168
- 29 + 45139 = 45168
- 31 + 45137 = 45168
- 37 + 45131 = 45168
- 41 + 45127 = 45168
- 47 + 45121 = 45168
- 107 + 45061 = 45168
- 181 + 44987 = 45168
Showing the first eight; more decompositions exist.
