Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505052, here are decompositions:

13 + 31505039 = 31505052
53 + 31504999 = 31505052
71 + 31504981 = 31505052
101 + 31504951 = 31505052
109 + 31504943 = 31505052
149 + 31504903 = 31505052
179 + 31504873 = 31505052
233 + 31504819 = 31505052

Showing the first eight; more decompositions exist.
