Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294961872, here are decompositions:
- 11 + 4294961861 = 4294961872
- 29 + 4294961843 = 4294961872
- 293 + 4294961579 = 4294961872
- 389 + 4294961483 = 4294961872
- 419 + 4294961453 = 4294961872
- 743 + 4294961129 = 4294961872
- 863 + 4294961009 = 4294961872
- 941 + 4294960931 = 4294961872
Showing the first eight; more decompositions exist.
