Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87422, here are decompositions:
- 19 + 87403 = 87422
- 109 + 87313 = 87422
- 199 + 87223 = 87422
- 211 + 87211 = 87422
- 241 + 87181 = 87422
- 271 + 87151 = 87422
- 373 + 87049 = 87422
- 409 + 87013 = 87422
Showing the first eight; more decompositions exist.
