Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91838, here are decompositions:
- 31 + 91807 = 91838
- 37 + 91801 = 91838
- 67 + 91771 = 91838
- 127 + 91711 = 91838
- 199 + 91639 = 91838
- 379 + 91459 = 91838
- 457 + 91381 = 91838
- 541 + 91297 = 91838
Showing the first eight; more decompositions exist.
