Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78478, here are decompositions:
- 11 + 78467 = 78478
- 41 + 78437 = 78478
- 131 + 78347 = 78478
- 137 + 78341 = 78478
- 167 + 78311 = 78478
- 311 + 78167 = 78478
- 419 + 78059 = 78478
- 461 + 78017 = 78478
Showing the first eight; more decompositions exist.
