Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158916, here are decompositions:
- 7 + 158909 = 158916
- 53 + 158863 = 158916
- 67 + 158849 = 158916
- 73 + 158843 = 158916
- 113 + 158803 = 158916
- 139 + 158777 = 158916
- 157 + 158759 = 158916
- 167 + 158749 = 158916
Showing the first eight; more decompositions exist.
