Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158236, here are decompositions:
- 3 + 158233 = 158236
- 5 + 158231 = 158236
- 47 + 158189 = 158236
- 107 + 158129 = 158236
- 227 + 158009 = 158236
- 233 + 158003 = 158236
- 347 + 157889 = 158236
- 359 + 157877 = 158236
Showing the first eight; more decompositions exist.
