Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145962, here are decompositions:
- 13 + 145949 = 145962
- 29 + 145933 = 145962
- 31 + 145931 = 145962
- 59 + 145903 = 145962
- 83 + 145879 = 145962
- 101 + 145861 = 145962
- 139 + 145823 = 145962
- 163 + 145799 = 145962
Showing the first eight; more decompositions exist.
