Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56420, here are decompositions:
- 3 + 56417 = 56420
- 19 + 56401 = 56420
- 37 + 56383 = 56420
- 43 + 56377 = 56420
- 61 + 56359 = 56420
- 109 + 56311 = 56420
- 151 + 56269 = 56420
- 157 + 56263 = 56420
Showing the first eight; more decompositions exist.
