Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21414, here are decompositions:
- 7 + 21407 = 21414
- 13 + 21401 = 21414
- 17 + 21397 = 21414
- 23 + 21391 = 21414
- 31 + 21383 = 21414
- 37 + 21377 = 21414
- 67 + 21347 = 21414
- 73 + 21341 = 21414
Showing the first eight; more decompositions exist.
