Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479366, here are decompositions:
- 29 + 31479337 = 31479366
- 59 + 31479307 = 31479366
- 67 + 31479299 = 31479366
- 89 + 31479277 = 31479366
- 97 + 31479269 = 31479366
- 239 + 31479127 = 31479366
- 283 + 31479083 = 31479366
- 293 + 31479073 = 31479366
Showing the first eight; more decompositions exist.
