Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947478, here are decompositions:
- 29 + 947449 = 947478
- 47 + 947431 = 947478
- 61 + 947417 = 947478
- 67 + 947411 = 947478
- 71 + 947407 = 947478
- 89 + 947389 = 947478
- 97 + 947381 = 947478
- 101 + 947377 = 947478
Showing the first eight; more decompositions exist.
