Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29040, here are decompositions:
- 7 + 29033 = 29040
- 13 + 29027 = 29040
- 17 + 29023 = 29040
- 19 + 29021 = 29040
- 23 + 29017 = 29040
- 31 + 29009 = 29040
- 61 + 28979 = 29040
- 79 + 28961 = 29040
Showing the first eight; more decompositions exist.
