Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90440, here are decompositions:
- 3 + 90437 = 90440
- 37 + 90403 = 90440
- 43 + 90397 = 90440
- 61 + 90379 = 90440
- 67 + 90373 = 90440
- 127 + 90313 = 90440
- 151 + 90289 = 90440
- 193 + 90247 = 90440
Showing the first eight; more decompositions exist.
