Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425028, here are decompositions:
- 79 + 2147424949 = 2147425028
- 211 + 2147424817 = 2147425028
- 241 + 2147424787 = 2147425028
- 439 + 2147424589 = 2147425028
- 547 + 2147424481 = 2147425028
- 601 + 2147424427 = 2147425028
- 769 + 2147424259 = 2147425028
- 1021 + 2147424007 = 2147425028
Showing the first eight; more decompositions exist.
