Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294977388, here are decompositions:
- 41 + 4294977347 = 4294977388
- 59 + 4294977329 = 4294977388
- 71 + 4294977317 = 4294977388
- 101 + 4294977287 = 4294977388
- 227 + 4294977161 = 4294977388
- 239 + 4294977149 = 4294977388
- 431 + 4294976957 = 4294977388
- 521 + 4294976867 = 4294977388
Showing the first eight; more decompositions exist.
