Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294958978, here are decompositions:
- 97 + 4294958881 = 4294958978
- 367 + 4294958611 = 4294958978
- 439 + 4294958539 = 4294958978
- 577 + 4294958401 = 4294958978
- 907 + 4294958071 = 4294958978
- 967 + 4294958011 = 4294958978
- 1021 + 4294957957 = 4294958978
- 1039 + 4294957939 = 4294958978
Showing the first eight; more decompositions exist.
