Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582464, here are decompositions:
- 47 + 31582417 = 31582464
- 61 + 31582403 = 31582464
- 127 + 31582337 = 31582464
- 131 + 31582333 = 31582464
- 197 + 31582267 = 31582464
- 223 + 31582241 = 31582464
- 257 + 31582207 = 31582464
- 271 + 31582193 = 31582464
Showing the first eight; more decompositions exist.
