Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87278, here are decompositions:
- 67 + 87211 = 87278
- 97 + 87181 = 87278
- 127 + 87151 = 87278
- 157 + 87121 = 87278
- 229 + 87049 = 87278
- 241 + 87037 = 87278
- 349 + 86929 = 87278
- 409 + 86869 = 87278
Showing the first eight; more decompositions exist.
