Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158980, here are decompositions:
- 53 + 158927 = 158980
- 71 + 158909 = 158980
- 113 + 158867 = 158980
- 131 + 158849 = 158980
- 137 + 158843 = 158980
- 233 + 158747 = 158980
- 281 + 158699 = 158980
- 317 + 158663 = 158980
Showing the first eight; more decompositions exist.
