Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425290, here are decompositions:
- 7 + 2147425283 = 2147425290
- 41 + 2147425249 = 2147425290
- 47 + 2147425243 = 2147425290
- 53 + 2147425237 = 2147425290
- 103 + 2147425187 = 2147425290
- 151 + 2147425139 = 2147425290
- 163 + 2147425127 = 2147425290
- 167 + 2147425123 = 2147425290
Showing the first eight; more decompositions exist.
