Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508872, here are decompositions:
- 5 + 508867 = 508872
- 31 + 508841 = 508872
- 61 + 508811 = 508872
- 73 + 508799 = 508872
- 83 + 508789 = 508872
- 101 + 508771 = 508872
- 163 + 508709 = 508872
- 179 + 508693 = 508872
Showing the first eight; more decompositions exist.
