Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449702, here are decompositions:
- 5 + 31449697 = 31449702
- 13 + 31449689 = 31449702
- 23 + 31449679 = 31449702
- 29 + 31449673 = 31449702
- 73 + 31449629 = 31449702
- 83 + 31449619 = 31449702
- 113 + 31449589 = 31449702
- 131 + 31449571 = 31449702
Showing the first eight; more decompositions exist.
