Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45172, here are decompositions:
- 11 + 45161 = 45172
- 41 + 45131 = 45172
- 53 + 45119 = 45172
- 89 + 45083 = 45172
- 233 + 44939 = 45172
- 263 + 44909 = 45172
- 293 + 44879 = 45172
- 353 + 44819 = 45172
Showing the first eight; more decompositions exist.
