Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28002, here are decompositions:
- 5 + 27997 = 28002
- 19 + 27983 = 28002
- 41 + 27961 = 28002
- 59 + 27943 = 28002
- 61 + 27941 = 28002
- 83 + 27919 = 28002
- 101 + 27901 = 28002
- 109 + 27893 = 28002
Showing the first eight; more decompositions exist.
