Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497872, here are decompositions:
- 3 + 497869 = 497872
- 5 + 497867 = 497872
- 41 + 497831 = 497872
- 59 + 497813 = 497872
- 71 + 497801 = 497872
- 101 + 497771 = 497872
- 131 + 497741 = 497872
- 239 + 497633 = 497872
Showing the first eight; more decompositions exist.
