Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12958, here are decompositions:
- 5 + 12953 = 12958
- 17 + 12941 = 12958
- 41 + 12917 = 12958
- 47 + 12911 = 12958
- 59 + 12899 = 12958
- 137 + 12821 = 12958
- 149 + 12809 = 12958
- 167 + 12791 = 12958
Showing the first eight; more decompositions exist.
