Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85970, here are decompositions:
- 37 + 85933 = 85970
- 61 + 85909 = 85970
- 67 + 85903 = 85970
- 127 + 85843 = 85970
- 139 + 85831 = 85970
- 151 + 85819 = 85970
- 331 + 85639 = 85970
- 349 + 85621 = 85970
Showing the first eight; more decompositions exist.
