Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49902, here are decompositions:
- 11 + 49891 = 49902
- 31 + 49871 = 49902
- 59 + 49843 = 49902
- 71 + 49831 = 49902
- 79 + 49823 = 49902
- 101 + 49801 = 49902
- 113 + 49789 = 49902
- 163 + 49739 = 49902
Showing the first eight; more decompositions exist.
