Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449670, here are decompositions:
- 23 + 31449647 = 31449670
- 41 + 31449629 = 31449670
- 59 + 31449611 = 31449670
- 89 + 31449581 = 31449670
- 101 + 31449569 = 31449670
- 113 + 31449557 = 31449670
- 191 + 31449479 = 31449670
- 269 + 31449401 = 31449670
Showing the first eight; more decompositions exist.
