Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42536, here are decompositions:
- 3 + 42533 = 42536
- 37 + 42499 = 42536
- 73 + 42463 = 42536
- 79 + 42457 = 42536
- 103 + 42433 = 42536
- 127 + 42409 = 42536
- 139 + 42397 = 42536
- 157 + 42379 = 42536
Showing the first eight; more decompositions exist.
