Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72524, here are decompositions:
- 31 + 72493 = 72524
- 43 + 72481 = 72524
- 103 + 72421 = 72524
- 157 + 72367 = 72524
- 211 + 72313 = 72524
- 271 + 72253 = 72524
- 313 + 72211 = 72524
- 421 + 72103 = 72524
Showing the first eight; more decompositions exist.
