Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2418, here are decompositions:
- 7 + 2411 = 2418
- 19 + 2399 = 2418
- 29 + 2389 = 2418
- 37 + 2381 = 2418
- 41 + 2377 = 2418
- 47 + 2371 = 2418
- 61 + 2357 = 2418
- 67 + 2351 = 2418
Showing the first eight; more decompositions exist.
