Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145956, here are decompositions:
- 7 + 145949 = 145956
- 23 + 145933 = 145956
- 53 + 145903 = 145956
- 59 + 145897 = 145956
- 127 + 145829 = 145956
- 137 + 145819 = 145956
- 149 + 145807 = 145956
- 157 + 145799 = 145956
Showing the first eight; more decompositions exist.
