Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73572, here are decompositions:
- 11 + 73561 = 73572
- 19 + 73553 = 73572
- 43 + 73529 = 73572
- 89 + 73483 = 73572
- 101 + 73471 = 73572
- 113 + 73459 = 73572
- 139 + 73433 = 73572
- 151 + 73421 = 73572
Showing the first eight; more decompositions exist.
