Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145174, here are decompositions:
- 41 + 145133 = 145174
- 53 + 145121 = 145174
- 83 + 145091 = 145174
- 131 + 145043 = 145174
- 137 + 145037 = 145174
- 167 + 145007 = 145174
- 191 + 144983 = 145174
- 233 + 144941 = 145174
Showing the first eight; more decompositions exist.
