Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49872, here are decompositions:
- 19 + 49853 = 49872
- 29 + 49843 = 49872
- 41 + 49831 = 49872
- 61 + 49811 = 49872
- 71 + 49801 = 49872
- 83 + 49789 = 49872
- 89 + 49783 = 49872
- 131 + 49741 = 49872
Showing the first eight; more decompositions exist.
