Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15126, here are decompositions:
- 5 + 15121 = 15126
- 19 + 15107 = 15126
- 43 + 15083 = 15126
- 53 + 15073 = 15126
- 73 + 15053 = 15126
- 109 + 15017 = 15126
- 113 + 15013 = 15126
- 157 + 14969 = 15126
Showing the first eight; more decompositions exist.
