Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28356, here are decompositions:
- 5 + 28351 = 28356
- 7 + 28349 = 28356
- 37 + 28319 = 28356
- 47 + 28309 = 28356
- 59 + 28297 = 28356
- 67 + 28289 = 28356
- 73 + 28283 = 28356
- 79 + 28277 = 28356
Showing the first eight; more decompositions exist.
