Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85370, here are decompositions:
- 7 + 85363 = 85370
- 37 + 85333 = 85370
- 67 + 85303 = 85370
- 73 + 85297 = 85370
- 127 + 85243 = 85370
- 157 + 85213 = 85370
- 211 + 85159 = 85370
- 223 + 85147 = 85370
Showing the first eight; more decompositions exist.
