Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37920, here are decompositions:
- 13 + 37907 = 37920
- 23 + 37897 = 37920
- 31 + 37889 = 37920
- 41 + 37879 = 37920
- 59 + 37861 = 37920
- 67 + 37853 = 37920
- 73 + 37847 = 37920
- 89 + 37831 = 37920
Showing the first eight; more decompositions exist.
