Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156238, here are decompositions:
- 11 + 156227 = 156238
- 107 + 156131 = 156238
- 149 + 156089 = 156238
- 167 + 156071 = 156238
- 179 + 156059 = 156238
- 197 + 156041 = 156238
- 227 + 156011 = 156238
- 317 + 155921 = 156238
Showing the first eight; more decompositions exist.
