Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188370, here are decompositions:
- 11 + 188359 = 188370
- 19 + 188351 = 188370
- 37 + 188333 = 188370
- 47 + 188323 = 188370
- 53 + 188317 = 188370
- 59 + 188311 = 188370
- 67 + 188303 = 188370
- 71 + 188299 = 188370
Showing the first eight; more decompositions exist.
