Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387396, here are decompositions:
- 3 + 2147387393 = 2147387396
- 13 + 2147387383 = 2147387396
- 73 + 2147387323 = 2147387396
- 97 + 2147387299 = 2147387396
- 139 + 2147387257 = 2147387396
- 313 + 2147387083 = 2147387396
- 337 + 2147387059 = 2147387396
- 367 + 2147387029 = 2147387396
Showing the first eight; more decompositions exist.
