Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938808, here are decompositions:
- 5 + 938803 = 938808
- 47 + 938761 = 938808
- 61 + 938747 = 938808
- 127 + 938681 = 938808
- 131 + 938677 = 938808
- 149 + 938659 = 938808
- 191 + 938617 = 938808
- 197 + 938611 = 938808
Showing the first eight; more decompositions exist.
