Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387082, here are decompositions:
- 19 + 2147387063 = 2147387082
- 23 + 2147387059 = 2147387082
- 53 + 2147387029 = 2147387082
- 73 + 2147387009 = 2147387082
- 79 + 2147387003 = 2147387082
- 199 + 2147386883 = 2147387082
- 229 + 2147386853 = 2147387082
- 349 + 2147386733 = 2147387082
Showing the first eight; more decompositions exist.
