Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498930, here are decompositions:
- 17 + 31498913 = 31498930
- 83 + 31498847 = 31498930
- 101 + 31498829 = 31498930
- 167 + 31498763 = 31498930
- 227 + 31498703 = 31498930
- 383 + 31498547 = 31498930
- 389 + 31498541 = 31498930
- 401 + 31498529 = 31498930
Showing the first eight; more decompositions exist.
