Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57420, here are decompositions:
- 7 + 57413 = 57420
- 23 + 57397 = 57420
- 31 + 57389 = 57420
- 37 + 57383 = 57420
- 47 + 57373 = 57420
- 53 + 57367 = 57420
- 71 + 57349 = 57420
- 73 + 57347 = 57420
Showing the first eight; more decompositions exist.
