Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20088, here are decompositions:
- 17 + 20071 = 20088
- 37 + 20051 = 20088
- 41 + 20047 = 20088
- 59 + 20029 = 20088
- 67 + 20021 = 20088
- 97 + 19991 = 20088
- 109 + 19979 = 20088
- 127 + 19961 = 20088
Showing the first eight; more decompositions exist.
