Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145694, here are decompositions:
- 7 + 145687 = 145694
- 13 + 145681 = 145694
- 61 + 145633 = 145694
- 151 + 145543 = 145694
- 163 + 145531 = 145694
- 181 + 145513 = 145694
- 193 + 145501 = 145694
- 223 + 145471 = 145694
Showing the first eight; more decompositions exist.
