Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156268, here are decompositions:
- 11 + 156257 = 156268
- 41 + 156227 = 156268
- 137 + 156131 = 156268
- 149 + 156119 = 156268
- 179 + 156089 = 156268
- 197 + 156071 = 156268
- 227 + 156041 = 156268
- 257 + 156011 = 156268
Showing the first eight; more decompositions exist.
