Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13030, here are decompositions:
- 23 + 13007 = 13030
- 29 + 13001 = 13030
- 47 + 12983 = 13030
- 71 + 12959 = 13030
- 89 + 12941 = 13030
- 107 + 12923 = 13030
- 113 + 12917 = 13030
- 131 + 12899 = 13030
Showing the first eight; more decompositions exist.
