Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147442970, here are decompositions:
- 173 + 2147442797 = 2147442970
- 293 + 2147442677 = 2147442970
- 347 + 2147442623 = 2147442970
- 503 + 2147442467 = 2147442970
- 557 + 2147442413 = 2147442970
- 839 + 2147442131 = 2147442970
- 941 + 2147442029 = 2147442970
- 971 + 2147441999 = 2147442970
Showing the first eight; more decompositions exist.
