Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78038, here are decompositions:
- 7 + 78031 = 78038
- 31 + 78007 = 78038
- 61 + 77977 = 78038
- 109 + 77929 = 78038
- 139 + 77899 = 78038
- 199 + 77839 = 78038
- 241 + 77797 = 78038
- 277 + 77761 = 78038
Showing the first eight; more decompositions exist.
