Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64442, here are decompositions:
- 3 + 64439 = 64442
- 43 + 64399 = 64442
- 61 + 64381 = 64442
- 109 + 64333 = 64442
- 139 + 64303 = 64442
- 163 + 64279 = 64442
- 211 + 64231 = 64442
- 271 + 64171 = 64442
Showing the first eight; more decompositions exist.
