Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38946, here are decompositions:
- 13 + 38933 = 38946
- 23 + 38923 = 38946
- 29 + 38917 = 38946
- 43 + 38903 = 38946
- 73 + 38873 = 38946
- 79 + 38867 = 38946
- 107 + 38839 = 38946
- 113 + 38833 = 38946
Showing the first eight; more decompositions exist.
