Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85340, here are decompositions:
- 7 + 85333 = 85340
- 37 + 85303 = 85340
- 43 + 85297 = 85340
- 97 + 85243 = 85340
- 103 + 85237 = 85340
- 127 + 85213 = 85340
- 139 + 85201 = 85340
- 181 + 85159 = 85340
Showing the first eight; more decompositions exist.
