Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72558, here are decompositions:
- 7 + 72551 = 72558
- 11 + 72547 = 72558
- 61 + 72497 = 72558
- 89 + 72469 = 72558
- 97 + 72461 = 72558
- 127 + 72431 = 72558
- 137 + 72421 = 72558
- 179 + 72379 = 72558
Showing the first eight; more decompositions exist.
