Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90618, here are decompositions:
- 19 + 90599 = 90618
- 71 + 90547 = 90618
- 89 + 90529 = 90618
- 107 + 90511 = 90618
- 137 + 90481 = 90618
- 149 + 90469 = 90618
- 179 + 90439 = 90618
- 181 + 90437 = 90618
Showing the first eight; more decompositions exist.
