Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147427718, here are decompositions:
- 17 + 2147427701 = 2147427718
- 41 + 2147427677 = 2147427718
- 71 + 2147427647 = 2147427718
- 167 + 2147427551 = 2147427718
- 509 + 2147427209 = 2147427718
- 677 + 2147427041 = 2147427718
- 971 + 2147426747 = 2147427718
- 1049 + 2147426669 = 2147427718
Showing the first eight; more decompositions exist.
