Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678408, here are decompositions:
- 97 + 8678311 = 8678408
- 229 + 8678179 = 8678408
- 379 + 8678029 = 8678408
- 397 + 8678011 = 8678408
- 457 + 8677951 = 8678408
- 727 + 8677681 = 8678408
- 757 + 8677651 = 8678408
- 1009 + 8677399 = 8678408
Showing the first eight; more decompositions exist.
