Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158994, here are decompositions:
- 13 + 158981 = 158994
- 53 + 158941 = 158994
- 67 + 158927 = 158994
- 71 + 158923 = 158994
- 113 + 158881 = 158994
- 127 + 158867 = 158994
- 131 + 158863 = 158994
- 151 + 158843 = 158994
Showing the first eight; more decompositions exist.
