Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147427428, here are decompositions:
- 31 + 2147427397 = 2147427428
- 199 + 2147427229 = 2147427428
- 271 + 2147427157 = 2147427428
- 277 + 2147427151 = 2147427428
- 337 + 2147427091 = 2147427428
- 439 + 2147426989 = 2147427428
- 457 + 2147426971 = 2147427428
- 607 + 2147426821 = 2147427428
Showing the first eight; more decompositions exist.
