Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29940, here are decompositions:
- 13 + 29927 = 29940
- 19 + 29921 = 29940
- 23 + 29917 = 29940
- 59 + 29881 = 29940
- 61 + 29879 = 29940
- 67 + 29873 = 29940
- 73 + 29867 = 29940
- 89 + 29851 = 29940
Showing the first eight; more decompositions exist.
