Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29130, here are decompositions:
- 7 + 29123 = 29130
- 29 + 29101 = 29130
- 53 + 29077 = 29130
- 67 + 29063 = 29130
- 71 + 29059 = 29130
- 97 + 29033 = 29130
- 103 + 29027 = 29130
- 107 + 29023 = 29130
Showing the first eight; more decompositions exist.
