Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85130, here are decompositions:
- 37 + 85093 = 85130
- 43 + 85087 = 85130
- 103 + 85027 = 85130
- 109 + 85021 = 85130
- 139 + 84991 = 85130
- 151 + 84979 = 85130
- 163 + 84967 = 85130
- 211 + 84919 = 85130
Showing the first eight; more decompositions exist.
