Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294968578, here are decompositions:
- 97 + 4294968481 = 4294968578
- 367 + 4294968211 = 4294968578
- 379 + 4294968199 = 4294968578
- 577 + 4294968001 = 4294968578
- 601 + 4294967977 = 4294968578
- 757 + 4294967821 = 4294968578
- 787 + 4294967791 = 4294968578
- 877 + 4294967701 = 4294968578
Showing the first eight; more decompositions exist.
