Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449526, here are decompositions:
- 47 + 31449479 = 31449526
- 149 + 31449377 = 31449526
- 167 + 31449359 = 31449526
- 239 + 31449287 = 31449526
- 263 + 31449263 = 31449526
- 293 + 31449233 = 31449526
- 347 + 31449179 = 31449526
- 443 + 31449083 = 31449526
Showing the first eight; more decompositions exist.
