Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78538, here are decompositions:
- 29 + 78509 = 78538
- 41 + 78497 = 78538
- 59 + 78479 = 78538
- 71 + 78467 = 78538
- 101 + 78437 = 78538
- 137 + 78401 = 78538
- 191 + 78347 = 78538
- 197 + 78341 = 78538
Showing the first eight; more decompositions exist.
