Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90480, here are decompositions:
- 7 + 90473 = 90480
- 11 + 90469 = 90480
- 41 + 90439 = 90480
- 43 + 90437 = 90480
- 73 + 90407 = 90480
- 79 + 90401 = 90480
- 83 + 90397 = 90480
- 101 + 90379 = 90480
Showing the first eight; more decompositions exist.
