Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7536, here are decompositions:
- 7 + 7529 = 7536
- 13 + 7523 = 7536
- 19 + 7517 = 7536
- 29 + 7507 = 7536
- 37 + 7499 = 7536
- 47 + 7489 = 7536
- 59 + 7477 = 7536
- 79 + 7457 = 7536
Showing the first eight; more decompositions exist.
