Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147429726, here are decompositions:
- 37 + 2147429689 = 2147429726
- 67 + 2147429659 = 2147429726
- 163 + 2147429563 = 2147429726
- 313 + 2147429413 = 2147429726
- 373 + 2147429353 = 2147429726
- 727 + 2147428999 = 2147429726
- 769 + 2147428957 = 2147429726
- 907 + 2147428819 = 2147429726
Showing the first eight; more decompositions exist.
