Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78136, here are decompositions:
- 137 + 77999 = 78136
- 167 + 77969 = 78136
- 269 + 77867 = 78136
- 353 + 77783 = 78136
- 389 + 77747 = 78136
- 449 + 77687 = 78136
- 563 + 77573 = 78136
- 587 + 77549 = 78136
Showing the first eight; more decompositions exist.
