Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 98990, here are decompositions:
- 37 + 98953 = 98990
- 43 + 98947 = 98990
- 61 + 98929 = 98990
- 79 + 98911 = 98990
- 97 + 98893 = 98990
- 103 + 98887 = 98990
- 181 + 98809 = 98990
- 211 + 98779 = 98990
Showing the first eight; more decompositions exist.
