Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147429318, here are decompositions:
- 7 + 2147429311 = 2147429318
- 37 + 2147429281 = 2147429318
- 271 + 2147429047 = 2147429318
- 337 + 2147428981 = 2147429318
- 457 + 2147428861 = 2147429318
- 499 + 2147428819 = 2147429318
- 631 + 2147428687 = 2147429318
- 757 + 2147428561 = 2147429318
Showing the first eight; more decompositions exist.
