Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732472, here are decompositions:
- 11 + 8732461 = 8732472
- 41 + 8732431 = 8732472
- 43 + 8732429 = 8732472
- 61 + 8732411 = 8732472
- 101 + 8732371 = 8732472
- 103 + 8732369 = 8732472
- 109 + 8732363 = 8732472
- 163 + 8732309 = 8732472
Showing the first eight; more decompositions exist.
