Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483272, here are decompositions:
- 3 + 2147483269 = 2147483272
- 23 + 2147483249 = 2147483272
- 101 + 2147483171 = 2147483272
- 149 + 2147483123 = 2147483272
- 239 + 2147483033 = 2147483272
- 461 + 2147482811 = 2147483272
- 509 + 2147482763 = 2147483272
- 863 + 2147482409 = 2147483272
Showing the first eight; more decompositions exist.
