Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72528, here are decompositions:
- 31 + 72497 = 72528
- 47 + 72481 = 72528
- 59 + 72469 = 72528
- 61 + 72467 = 72528
- 67 + 72461 = 72528
- 97 + 72431 = 72528
- 107 + 72421 = 72528
- 149 + 72379 = 72528
Showing the first eight; more decompositions exist.
