Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13038, here are decompositions:
- 5 + 13033 = 13038
- 29 + 13009 = 13038
- 31 + 13007 = 13038
- 37 + 13001 = 13038
- 59 + 12979 = 13038
- 71 + 12967 = 13038
- 79 + 12959 = 13038
- 97 + 12941 = 13038
Showing the first eight; more decompositions exist.
