Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147476562, here are decompositions:
- 19 + 2147476543 = 2147476562
- 43 + 2147476519 = 2147476562
- 163 + 2147476399 = 2147476562
- 181 + 2147476381 = 2147476562
- 241 + 2147476321 = 2147476562
- 271 + 2147476291 = 2147476562
- 313 + 2147476249 = 2147476562
- 379 + 2147476183 = 2147476562
Showing the first eight; more decompositions exist.
