Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156040, here are decompositions:
- 29 + 156011 = 156040
- 149 + 155891 = 156040
- 179 + 155861 = 156040
- 191 + 155849 = 156040
- 239 + 155801 = 156040
- 257 + 155783 = 156040
- 263 + 155777 = 156040
- 293 + 155747 = 156040
Showing the first eight; more decompositions exist.
