Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158232, here are decompositions:
- 5 + 158227 = 158232
- 23 + 158209 = 158232
- 31 + 158201 = 158232
- 43 + 158189 = 158232
- 71 + 158161 = 158232
- 89 + 158143 = 158232
- 103 + 158129 = 158232
- 223 + 158009 = 158232
Showing the first eight; more decompositions exist.
