Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147477012, here are decompositions:
- 61 + 2147476951 = 2147477012
- 193 + 2147476819 = 2147477012
- 223 + 2147476789 = 2147477012
- 271 + 2147476741 = 2147477012
- 313 + 2147476699 = 2147477012
- 349 + 2147476663 = 2147477012
- 613 + 2147476399 = 2147477012
- 631 + 2147476381 = 2147477012
Showing the first eight; more decompositions exist.
