Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972840, here are decompositions:
- 17 + 4294972823 = 4294972840
- 47 + 4294972793 = 4294972840
- 89 + 4294972751 = 4294972840
- 113 + 4294972727 = 4294972840
- 227 + 4294972613 = 4294972840
- 281 + 4294972559 = 4294972840
- 359 + 4294972481 = 4294972840
- 419 + 4294972421 = 4294972840
Showing the first eight; more decompositions exist.
