Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45158, here are decompositions:
- 19 + 45139 = 45158
- 31 + 45127 = 45158
- 37 + 45121 = 45158
- 97 + 45061 = 45158
- 151 + 45007 = 45158
- 199 + 44959 = 45158
- 241 + 44917 = 45158
- 271 + 44887 = 45158
Showing the first eight; more decompositions exist.
