Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294973978, here are decompositions:
- 67 + 4294973911 = 4294973978
- 79 + 4294973899 = 4294973978
- 109 + 4294973869 = 4294973978
- 307 + 4294973671 = 4294973978
- 349 + 4294973629 = 4294973978
- 367 + 4294973611 = 4294973978
- 409 + 4294973569 = 4294973978
- 439 + 4294973539 = 4294973978
Showing the first eight; more decompositions exist.
