Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90878, here are decompositions:
- 31 + 90847 = 90878
- 37 + 90841 = 90878
- 181 + 90697 = 90878
- 199 + 90679 = 90878
- 331 + 90547 = 90878
- 349 + 90529 = 90878
- 367 + 90511 = 90878
- 379 + 90499 = 90878
Showing the first eight; more decompositions exist.
