Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525978, here are decompositions:
- 17 + 525961 = 525978
- 29 + 525949 = 525978
- 31 + 525947 = 525978
- 41 + 525937 = 525978
- 107 + 525871 = 525978
- 109 + 525869 = 525978
- 139 + 525839 = 525978
- 197 + 525781 = 525978
Showing the first eight; more decompositions exist.
