Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610880, here are decompositions:
- 13 + 31610867 = 31610880
- 89 + 31610791 = 31610880
- 101 + 31610779 = 31610880
- 107 + 31610773 = 31610880
- 109 + 31610771 = 31610880
- 139 + 31610741 = 31610880
- 151 + 31610729 = 31610880
- 157 + 31610723 = 31610880
Showing the first eight; more decompositions exist.
