Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462030, here are decompositions:

23 + 31462007 = 31462030
53 + 31461977 = 31462030
107 + 31461923 = 31462030
137 + 31461893 = 31462030
179 + 31461851 = 31462030
239 + 31461791 = 31462030
251 + 31461779 = 31462030
269 + 31461761 = 31462030

Showing the first eight; more decompositions exist.
