Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155908, here are decompositions:
- 17 + 155891 = 155908
- 47 + 155861 = 155908
- 59 + 155849 = 155908
- 107 + 155801 = 155908
- 131 + 155777 = 155908
- 167 + 155741 = 155908
- 191 + 155717 = 155908
- 251 + 155657 = 155908
Showing the first eight; more decompositions exist.
