Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90920, here are decompositions:
- 3 + 90917 = 90920
- 13 + 90907 = 90920
- 19 + 90901 = 90920
- 73 + 90847 = 90920
- 79 + 90841 = 90920
- 97 + 90823 = 90920
- 127 + 90793 = 90920
- 211 + 90709 = 90920
Showing the first eight; more decompositions exist.
