Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294973990, here are decompositions:
- 3 + 4294973987 = 4294973990
- 37 + 4294973953 = 4294973990
- 67 + 4294973923 = 4294973990
- 79 + 4294973911 = 4294973990
- 199 + 4294973791 = 4294973990
- 277 + 4294973713 = 4294973990
- 379 + 4294973611 = 4294973990
- 397 + 4294973593 = 4294973990
Showing the first eight; more decompositions exist.
