Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626030, here are decompositions:

11 + 31626019 = 31626030
19 + 31626011 = 31626030
43 + 31625987 = 31626030
61 + 31625969 = 31626030
67 + 31625963 = 31626030
113 + 31625917 = 31626030
181 + 31625849 = 31626030
211 + 31625819 = 31626030

Showing the first eight; more decompositions exist.
