Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147429702, here are decompositions:
- 13 + 2147429689 = 2147429702
- 43 + 2147429659 = 2147429702
- 139 + 2147429563 = 2147429702
- 349 + 2147429353 = 2147429702
- 421 + 2147429281 = 2147429702
- 571 + 2147429131 = 2147429702
- 631 + 2147429071 = 2147429702
- 811 + 2147428891 = 2147429702
Showing the first eight; more decompositions exist.
