Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147428232, here are decompositions:
- 139 + 2147428093 = 2147428232
- 163 + 2147428069 = 2147428232
- 211 + 2147428021 = 2147428232
- 283 + 2147427949 = 2147428232
- 331 + 2147427901 = 2147428232
- 349 + 2147427883 = 2147428232
- 373 + 2147427859 = 2147428232
- 1063 + 2147427169 = 2147428232
Showing the first eight; more decompositions exist.
