Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31694, here are decompositions:
- 7 + 31687 = 31694
- 31 + 31663 = 31694
- 37 + 31657 = 31694
- 67 + 31627 = 31694
- 127 + 31567 = 31694
- 151 + 31543 = 31694
- 163 + 31531 = 31694
- 181 + 31513 = 31694
Showing the first eight; more decompositions exist.
