Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449694, here are decompositions:
- 5 + 31449689 = 31449694
- 47 + 31449647 = 31449694
- 83 + 31449611 = 31449694
- 113 + 31449581 = 31449694
- 137 + 31449557 = 31449694
- 167 + 31449527 = 31449694
- 293 + 31449401 = 31449694
- 317 + 31449377 = 31449694
Showing the first eight; more decompositions exist.
