Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483080, here are decompositions:
- 11 + 31483069 = 31483080
- 19 + 31483061 = 31483080
- 29 + 31483051 = 31483080
- 89 + 31482991 = 31483080
- 103 + 31482977 = 31483080
- 107 + 31482973 = 31483080
- 173 + 31482907 = 31483080
- 191 + 31482889 = 31483080
Showing the first eight; more decompositions exist.
