Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85424, here are decompositions:
- 13 + 85411 = 85424
- 43 + 85381 = 85424
- 61 + 85363 = 85424
- 127 + 85297 = 85424
- 181 + 85243 = 85424
- 211 + 85213 = 85424
- 223 + 85201 = 85424
- 277 + 85147 = 85424
Showing the first eight; more decompositions exist.
