Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22072, here are decompositions:
- 5 + 22067 = 22072
- 41 + 22031 = 22072
- 59 + 22013 = 22072
- 179 + 21893 = 22072
- 191 + 21881 = 22072
- 233 + 21839 = 22072
- 251 + 21821 = 22072
- 269 + 21803 = 22072
Showing the first eight; more decompositions exist.
