Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550382, here are decompositions:

11 + 31550371 = 31550382
29 + 31550353 = 31550382
43 + 31550339 = 31550382
53 + 31550329 = 31550382
131 + 31550251 = 31550382
181 + 31550201 = 31550382
229 + 31550153 = 31550382
233 + 31550149 = 31550382

Showing the first eight; more decompositions exist.
