Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85158, here are decompositions:
- 11 + 85147 = 85158
- 37 + 85121 = 85158
- 67 + 85091 = 85158
- 71 + 85087 = 85158
- 97 + 85061 = 85158
- 109 + 85049 = 85158
- 131 + 85027 = 85158
- 137 + 85021 = 85158
Showing the first eight; more decompositions exist.
