Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118470, here are decompositions:
- 7 + 118463 = 118470
- 13 + 118457 = 118470
- 17 + 118453 = 118470
- 41 + 118429 = 118470
- 47 + 118423 = 118470
- 59 + 118411 = 118470
- 61 + 118409 = 118470
- 71 + 118399 = 118470
Showing the first eight; more decompositions exist.
