Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564970, here are decompositions:
- 37 + 31564933 = 31564970
- 43 + 31564927 = 31564970
- 79 + 31564891 = 31564970
- 97 + 31564873 = 31564970
- 139 + 31564831 = 31564970
- 163 + 31564807 = 31564970
- 313 + 31564657 = 31564970
- 331 + 31564639 = 31564970
Showing the first eight; more decompositions exist.
