Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460960, here are decompositions:
- 31 + 31460929 = 31460960
- 43 + 31460917 = 31460960
- 109 + 31460851 = 31460960
- 127 + 31460833 = 31460960
- 151 + 31460809 = 31460960
- 283 + 31460677 = 31460960
- 313 + 31460647 = 31460960
- 379 + 31460581 = 31460960
Showing the first eight; more decompositions exist.
