Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294973278, here are decompositions:
- 5 + 4294973273 = 4294973278
- 47 + 4294973231 = 4294973278
- 131 + 4294973147 = 4294973278
- 179 + 4294973099 = 4294973278
- 347 + 4294972931 = 4294973278
- 419 + 4294972859 = 4294973278
- 719 + 4294972559 = 4294973278
- 797 + 4294972481 = 4294973278
Showing the first eight; more decompositions exist.
