Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21134, here are decompositions:
- 13 + 21121 = 21134
- 67 + 21067 = 21134
- 73 + 21061 = 21134
- 103 + 21031 = 21134
- 151 + 20983 = 21134
- 277 + 20857 = 21134
- 523 + 20611 = 21134
- 541 + 20593 = 21134
Showing the first eight; more decompositions exist.
