Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147478370, here are decompositions:
- 71 + 2147478299 = 2147478370
- 281 + 2147478089 = 2147478370
- 353 + 2147478017 = 2147478370
- 491 + 2147477879 = 2147478370
- 509 + 2147477861 = 2147478370
- 563 + 2147477807 = 2147478370
- 683 + 2147477687 = 2147478370
- 743 + 2147477627 = 2147478370
Showing the first eight; more decompositions exist.
