Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147427230, here are decompositions:
- 61 + 2147427169 = 2147427230
- 73 + 2147427157 = 2147427230
- 79 + 2147427151 = 2147427230
- 139 + 2147427091 = 2147427230
- 229 + 2147427001 = 2147427230
- 241 + 2147426989 = 2147427230
- 409 + 2147426821 = 2147427230
- 601 + 2147426629 = 2147427230
Showing the first eight; more decompositions exist.
