Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425602, here are decompositions:
- 11 + 2147425591 = 2147425602
- 43 + 2147425559 = 2147425602
- 61 + 2147425541 = 2147425602
- 71 + 2147425531 = 2147425602
- 83 + 2147425519 = 2147425602
- 89 + 2147425513 = 2147425602
- 149 + 2147425453 = 2147425602
- 191 + 2147425411 = 2147425602
Showing the first eight; more decompositions exist.
