Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28136, here are decompositions:
- 13 + 28123 = 28136
- 37 + 28099 = 28136
- 67 + 28069 = 28136
- 79 + 28057 = 28136
- 109 + 28027 = 28136
- 139 + 27997 = 28136
- 193 + 27943 = 28136
- 313 + 27823 = 28136
Showing the first eight; more decompositions exist.
