Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56780, here are decompositions:
- 7 + 56773 = 56780
- 13 + 56767 = 56780
- 43 + 56737 = 56780
- 67 + 56713 = 56780
- 79 + 56701 = 56780
- 109 + 56671 = 56780
- 151 + 56629 = 56780
- 181 + 56599 = 56780
Showing the first eight; more decompositions exist.
