Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294977172, here are decompositions:
- 11 + 4294977161 = 4294977172
- 23 + 4294977149 = 4294977172
- 89 + 4294977083 = 4294977172
- 149 + 4294977023 = 4294977172
- 191 + 4294976981 = 4294977172
- 449 + 4294976723 = 4294977172
- 593 + 4294976579 = 4294977172
- 653 + 4294976519 = 4294977172
Showing the first eight; more decompositions exist.
