Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13012, here are decompositions:
- 3 + 13009 = 13012
- 5 + 13007 = 13012
- 11 + 13001 = 13012
- 29 + 12983 = 13012
- 53 + 12959 = 13012
- 59 + 12953 = 13012
- 71 + 12941 = 13012
- 89 + 12923 = 13012
Showing the first eight; more decompositions exist.
