Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611242, here are decompositions:
- 79 + 31611163 = 31611242
- 193 + 31611049 = 31611242
- 199 + 31611043 = 31611242
- 331 + 31610911 = 31611242
- 349 + 31610893 = 31611242
- 463 + 31610779 = 31611242
- 601 + 31610641 = 31611242
- 613 + 31610629 = 31611242
Showing the first eight; more decompositions exist.
