Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84270, here are decompositions:
- 7 + 84263 = 84270
- 23 + 84247 = 84270
- 31 + 84239 = 84270
- 41 + 84229 = 84270
- 47 + 84223 = 84270
- 59 + 84211 = 84270
- 71 + 84199 = 84270
- 79 + 84191 = 84270
Showing the first eight; more decompositions exist.
