Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91040, here are decompositions:
- 7 + 91033 = 91040
- 31 + 91009 = 91040
- 43 + 90997 = 91040
- 109 + 90931 = 91040
- 139 + 90901 = 91040
- 193 + 90847 = 91040
- 199 + 90841 = 91040
- 331 + 90709 = 91040
Showing the first eight; more decompositions exist.
