Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158678, here are decompositions:
- 31 + 158647 = 158678
- 61 + 158617 = 158678
- 67 + 158611 = 158678
- 97 + 158581 = 158678
- 127 + 158551 = 158678
- 151 + 158527 = 158678
- 229 + 158449 = 158678
- 271 + 158407 = 158678
Showing the first eight; more decompositions exist.
