Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31976, here are decompositions:
- 3 + 31973 = 31976
- 13 + 31963 = 31976
- 19 + 31957 = 31976
- 103 + 31873 = 31976
- 127 + 31849 = 31976
- 277 + 31699 = 31976
- 313 + 31663 = 31976
- 349 + 31627 = 31976
Showing the first eight; more decompositions exist.
