Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690250, here are decompositions:
- 29 + 8690221 = 8690250
- 47 + 8690203 = 8690250
- 59 + 8690191 = 8690250
- 73 + 8690177 = 8690250
- 131 + 8690119 = 8690250
- 157 + 8690093 = 8690250
- 181 + 8690069 = 8690250
- 263 + 8689987 = 8690250
Showing the first eight; more decompositions exist.
