Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78738, here are decompositions:
- 17 + 78721 = 78738
- 31 + 78707 = 78738
- 41 + 78697 = 78738
- 47 + 78691 = 78738
- 89 + 78649 = 78738
- 131 + 78607 = 78738
- 167 + 78571 = 78738
- 197 + 78541 = 78738
Showing the first eight; more decompositions exist.
