Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78818, here are decompositions:
- 31 + 78787 = 78818
- 37 + 78781 = 78818
- 97 + 78721 = 78818
- 127 + 78691 = 78818
- 211 + 78607 = 78818
- 241 + 78577 = 78818
- 277 + 78541 = 78818
- 307 + 78511 = 78818
Showing the first eight; more decompositions exist.
