Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28236, here are decompositions:
- 7 + 28229 = 28236
- 17 + 28219 = 28236
- 53 + 28183 = 28236
- 73 + 28163 = 28236
- 113 + 28123 = 28236
- 127 + 28109 = 28236
- 137 + 28099 = 28236
- 139 + 28097 = 28236
Showing the first eight; more decompositions exist.
