Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294961172, here are decompositions:
- 43 + 4294961129 = 4294961172
- 53 + 4294961119 = 4294961172
- 101 + 4294961071 = 4294961172
- 149 + 4294961023 = 4294961172
- 163 + 4294961009 = 4294961172
- 191 + 4294960981 = 4294961172
- 193 + 4294960979 = 4294961172
- 199 + 4294960973 = 4294961172
Showing the first eight; more decompositions exist.
