Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425080, here are decompositions:
- 7 + 2147425073 = 2147425080
- 13 + 2147425067 = 2147425080
- 79 + 2147425001 = 2147425080
- 131 + 2147424949 = 2147425080
- 167 + 2147424913 = 2147425080
- 181 + 2147424899 = 2147425080
- 211 + 2147424869 = 2147425080
- 263 + 2147424817 = 2147425080
Showing the first eight; more decompositions exist.
