Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91880, here are decompositions:
- 7 + 91873 = 91880
- 13 + 91867 = 91880
- 43 + 91837 = 91880
- 67 + 91813 = 91880
- 73 + 91807 = 91880
- 79 + 91801 = 91880
- 109 + 91771 = 91880
- 127 + 91753 = 91880
Showing the first eight; more decompositions exist.
