Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155948, here are decompositions:
- 61 + 155887 = 155948
- 97 + 155851 = 155948
- 127 + 155821 = 155948
- 139 + 155809 = 155948
- 151 + 155797 = 155948
- 229 + 155719 = 155948
- 241 + 155707 = 155948
- 277 + 155671 = 155948
Showing the first eight; more decompositions exist.
