Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57380, here are decompositions:
- 7 + 57373 = 57380
- 13 + 57367 = 57380
- 31 + 57349 = 57380
- 79 + 57301 = 57380
- 97 + 57283 = 57380
- 109 + 57271 = 57380
- 139 + 57241 = 57380
- 157 + 57223 = 57380
Showing the first eight; more decompositions exist.
