Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91616, here are decompositions:
- 43 + 91573 = 91616
- 103 + 91513 = 91616
- 157 + 91459 = 91616
- 163 + 91453 = 91616
- 193 + 91423 = 91616
- 223 + 91393 = 91616
- 229 + 91387 = 91616
- 307 + 91309 = 91616
Showing the first eight; more decompositions exist.
