Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473948, here are decompositions:
- 167 + 2147473781 = 2147473948
- 251 + 2147473697 = 2147473948
- 461 + 2147473487 = 2147473948
- 479 + 2147473469 = 2147473948
- 617 + 2147473331 = 2147473948
- 647 + 2147473301 = 2147473948
- 761 + 2147473187 = 2147473948
- 797 + 2147473151 = 2147473948
Showing the first eight; more decompositions exist.
