Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147426104, here are decompositions:
- 23 + 2147426081 = 2147426104
- 101 + 2147426003 = 2147426104
- 167 + 2147425937 = 2147426104
- 233 + 2147425871 = 2147426104
- 251 + 2147425853 = 2147426104
- 563 + 2147425541 = 2147426104
- 647 + 2147425457 = 2147426104
- 821 + 2147425283 = 2147426104
Showing the first eight; more decompositions exist.
