Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7472, here are decompositions:
- 13 + 7459 = 7472
- 61 + 7411 = 7472
- 79 + 7393 = 7472
- 103 + 7369 = 7472
- 139 + 7333 = 7472
- 151 + 7321 = 7472
- 163 + 7309 = 7472
- 229 + 7243 = 7472
Showing the first eight; more decompositions exist.
