Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158272, here are decompositions:
- 3 + 158269 = 158272
- 11 + 158261 = 158272
- 29 + 158243 = 158272
- 41 + 158231 = 158272
- 71 + 158201 = 158272
- 83 + 158189 = 158272
- 131 + 158141 = 158272
- 263 + 158009 = 158272
Showing the first eight; more decompositions exist.
