Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294960978, here are decompositions:
- 5 + 4294960973 = 4294960978
- 29 + 4294960949 = 4294960978
- 47 + 4294960931 = 4294960978
- 59 + 4294960919 = 4294960978
- 71 + 4294960907 = 4294960978
- 89 + 4294960889 = 4294960978
- 101 + 4294960877 = 4294960978
- 149 + 4294960829 = 4294960978
Showing the first eight; more decompositions exist.
