Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72636, here are decompositions:
- 13 + 72623 = 72636
- 19 + 72617 = 72636
- 23 + 72613 = 72636
- 59 + 72577 = 72636
- 89 + 72547 = 72636
- 103 + 72533 = 72636
- 139 + 72497 = 72636
- 167 + 72469 = 72636
Showing the first eight; more decompositions exist.
