Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90978, here are decompositions:
- 7 + 90971 = 90978
- 31 + 90947 = 90978
- 47 + 90931 = 90978
- 61 + 90917 = 90978
- 67 + 90911 = 90978
- 71 + 90907 = 90978
- 131 + 90847 = 90978
- 137 + 90841 = 90978
Showing the first eight; more decompositions exist.
