Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498960, here are decompositions:
- 11 + 31498949 = 31498960
- 29 + 31498931 = 31498960
- 47 + 31498913 = 31498960
- 107 + 31498853 = 31498960
- 113 + 31498847 = 31498960
- 131 + 31498829 = 31498960
- 149 + 31498811 = 31498960
- 197 + 31498763 = 31498960
Showing the first eight; more decompositions exist.
