Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139952, here are decompositions:
- 13 + 139939 = 139952
- 31 + 139921 = 139952
- 61 + 139891 = 139952
- 139 + 139813 = 139952
- 151 + 139801 = 139952
- 193 + 139759 = 139952
- 199 + 139753 = 139952
- 223 + 139729 = 139952
Showing the first eight; more decompositions exist.
