Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72522, here are decompositions:
- 19 + 72503 = 72522
- 29 + 72493 = 72522
- 41 + 72481 = 72522
- 53 + 72469 = 72522
- 61 + 72461 = 72522
- 101 + 72421 = 72522
- 139 + 72383 = 72522
- 181 + 72341 = 72522
Showing the first eight; more decompositions exist.
