Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158308, here are decompositions:
- 5 + 158303 = 158308
- 47 + 158261 = 158308
- 107 + 158201 = 158308
- 167 + 158141 = 158308
- 179 + 158129 = 158308
- 317 + 157991 = 158308
- 401 + 157907 = 158308
- 419 + 157889 = 158308
Showing the first eight; more decompositions exist.
