Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147474246, here are decompositions:
- 7 + 2147474239 = 2147474246
- 97 + 2147474149 = 2147474246
- 283 + 2147473963 = 2147474246
- 349 + 2147473897 = 2147474246
- 397 + 2147473849 = 2147474246
- 409 + 2147473837 = 2147474246
- 769 + 2147473477 = 2147474246
- 877 + 2147473369 = 2147474246
Showing the first eight; more decompositions exist.
