Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147429018, here are decompositions:
- 19 + 2147428999 = 2147429018
- 37 + 2147428981 = 2147429018
- 61 + 2147428957 = 2147429018
- 127 + 2147428891 = 2147429018
- 157 + 2147428861 = 2147429018
- 181 + 2147428837 = 2147429018
- 199 + 2147428819 = 2147429018
- 331 + 2147428687 = 2147429018
Showing the first eight; more decompositions exist.
