Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156028, here are decompositions:
- 17 + 156011 = 156028
- 107 + 155921 = 156028
- 137 + 155891 = 156028
- 167 + 155861 = 156028
- 179 + 155849 = 156028
- 227 + 155801 = 156028
- 251 + 155777 = 156028
- 281 + 155747 = 156028
Showing the first eight; more decompositions exist.
