Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147378204, here are decompositions:
- 3 + 2147378201 = 2147378204
- 73 + 2147378131 = 2147378204
- 193 + 2147378011 = 2147378204
- 277 + 2147377927 = 2147378204
- 463 + 2147377741 = 2147378204
- 571 + 2147377633 = 2147378204
- 613 + 2147377591 = 2147378204
- 823 + 2147377381 = 2147378204
Showing the first eight; more decompositions exist.
