Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145936, here are decompositions:
- 3 + 145933 = 145936
- 5 + 145931 = 145936
- 107 + 145829 = 145936
- 113 + 145823 = 145936
- 137 + 145799 = 145936
- 179 + 145757 = 145936
- 227 + 145709 = 145936
- 233 + 145703 = 145936
Showing the first eight; more decompositions exist.
