Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158518, here are decompositions:
- 11 + 158507 = 158518
- 29 + 158489 = 158518
- 89 + 158429 = 158518
- 167 + 158351 = 158518
- 257 + 158261 = 158518
- 317 + 158201 = 158518
- 389 + 158129 = 158518
- 509 + 158009 = 158518
Showing the first eight; more decompositions exist.
