Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990088, here are decompositions:
- 89 + 989999 = 990088
- 107 + 989981 = 990088
- 137 + 989951 = 990088
- 149 + 989939 = 990088
- 167 + 989921 = 990088
- 179 + 989909 = 990088
- 251 + 989837 = 990088
- 257 + 989831 = 990088
Showing the first eight; more decompositions exist.
