Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425562, here are decompositions:
- 3 + 2147425559 = 2147425562
- 31 + 2147425531 = 2147425562
- 43 + 2147425519 = 2147425562
- 109 + 2147425453 = 2147425562
- 151 + 2147425411 = 2147425562
- 181 + 2147425381 = 2147425562
- 229 + 2147425333 = 2147425562
- 313 + 2147425249 = 2147425562
Showing the first eight; more decompositions exist.
