Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506004, here are decompositions:

11 + 31505993 = 31506004
83 + 31505921 = 31506004
191 + 31505813 = 31506004
197 + 31505807 = 31506004
263 + 31505741 = 31506004
281 + 31505723 = 31506004
311 + 31505693 = 31506004
347 + 31505657 = 31506004

Showing the first eight; more decompositions exist.
