Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425246, here are decompositions:
- 3 + 2147425243 = 2147425246
- 59 + 2147425187 = 2147425246
- 107 + 2147425139 = 2147425246
- 173 + 2147425073 = 2147425246
- 179 + 2147425067 = 2147425246
- 347 + 2147424899 = 2147425246
- 353 + 2147424893 = 2147425246
- 383 + 2147424863 = 2147425246
Showing the first eight; more decompositions exist.
