Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57638, here are decompositions:
- 37 + 57601 = 57638
- 67 + 57571 = 57638
- 79 + 57559 = 57638
- 109 + 57529 = 57638
- 151 + 57487 = 57638
- 181 + 57457 = 57638
- 211 + 57427 = 57638
- 241 + 57397 = 57638
Showing the first eight; more decompositions exist.
