Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158038, here are decompositions:
- 29 + 158009 = 158038
- 47 + 157991 = 158038
- 107 + 157931 = 158038
- 131 + 157907 = 158038
- 137 + 157901 = 158038
- 149 + 157889 = 158038
- 197 + 157841 = 158038
- 239 + 157799 = 158038
Showing the first eight; more decompositions exist.
