Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45170, here are decompositions:
- 31 + 45139 = 45170
- 43 + 45127 = 45170
- 109 + 45061 = 45170
- 157 + 45013 = 45170
- 163 + 45007 = 45170
- 199 + 44971 = 45170
- 211 + 44959 = 45170
- 277 + 44893 = 45170
Showing the first eight; more decompositions exist.
