Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38930, here are decompositions:
- 7 + 38923 = 38930
- 13 + 38917 = 38930
- 79 + 38851 = 38930
- 97 + 38833 = 38930
- 109 + 38821 = 38930
- 127 + 38803 = 38930
- 139 + 38791 = 38930
- 163 + 38767 = 38930
Showing the first eight; more decompositions exist.
