Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294961438, here are decompositions:
- 37 + 4294961401 = 4294961438
- 151 + 4294961287 = 4294961438
- 241 + 4294961197 = 4294961438
- 367 + 4294961071 = 4294961438
- 457 + 4294960981 = 4294961438
- 487 + 4294960951 = 4294961438
- 601 + 4294960837 = 4294961438
- 877 + 4294960561 = 4294961438
Showing the first eight; more decompositions exist.
