Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86438, here are decompositions:
- 67 + 86371 = 86438
- 97 + 86341 = 86438
- 127 + 86311 = 86438
- 151 + 86287 = 86438
- 181 + 86257 = 86438
- 199 + 86239 = 86438
- 229 + 86209 = 86438
- 241 + 86197 = 86438
Showing the first eight; more decompositions exist.
