Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147429708, here are decompositions:
- 19 + 2147429689 = 2147429708
- 97 + 2147429611 = 2147429708
- 241 + 2147429467 = 2147429708
- 397 + 2147429311 = 2147429708
- 577 + 2147429131 = 2147429708
- 661 + 2147429047 = 2147429708
- 709 + 2147428999 = 2147429708
- 727 + 2147428981 = 2147429708
Showing the first eight; more decompositions exist.
