Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718472, here are decompositions:
- 3 + 8718469 = 8718472
- 11 + 8718461 = 8718472
- 41 + 8718431 = 8718472
- 53 + 8718419 = 8718472
- 71 + 8718401 = 8718472
- 251 + 8718221 = 8718472
- 281 + 8718191 = 8718472
- 359 + 8718113 = 8718472
Showing the first eight; more decompositions exist.
