Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749072, here are decompositions:
- 23 + 8749049 = 8749072
- 53 + 8749019 = 8749072
- 71 + 8749001 = 8749072
- 83 + 8748989 = 8749072
- 179 + 8748893 = 8749072
- 191 + 8748881 = 8749072
- 251 + 8748821 = 8749072
- 359 + 8748713 = 8749072
Showing the first eight; more decompositions exist.
