Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972128, here are decompositions:
- 11 + 4294972117 = 4294972128
- 19 + 4294972109 = 4294972128
- 59 + 4294972069 = 4294972128
- 67 + 4294972061 = 4294972128
- 79 + 4294972049 = 4294972128
- 89 + 4294972039 = 4294972128
- 137 + 4294971991 = 4294972128
- 191 + 4294971937 = 4294972128
Showing the first eight; more decompositions exist.
