Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45738, here are decompositions:
- 31 + 45707 = 45738
- 41 + 45697 = 45738
- 47 + 45691 = 45738
- 61 + 45677 = 45738
- 71 + 45667 = 45738
- 79 + 45659 = 45738
- 97 + 45641 = 45738
- 107 + 45631 = 45738
Showing the first eight; more decompositions exist.
