Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115158, here are decompositions:
- 5 + 115153 = 115158
- 7 + 115151 = 115158
- 31 + 115127 = 115158
- 41 + 115117 = 115158
- 59 + 115099 = 115158
- 79 + 115079 = 115158
- 97 + 115061 = 115158
- 101 + 115057 = 115158
Showing the first eight; more decompositions exist.
