Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425074, here are decompositions:
- 7 + 2147425067 = 2147425074
- 73 + 2147425001 = 2147425074
- 181 + 2147424893 = 2147425074
- 211 + 2147424863 = 2147425074
- 257 + 2147424817 = 2147425074
- 281 + 2147424793 = 2147425074
- 433 + 2147424641 = 2147425074
- 491 + 2147424583 = 2147425074
Showing the first eight; more decompositions exist.
