Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544082, here are decompositions:

5 + 31544077 = 31544082
29 + 31544053 = 31544082
41 + 31544041 = 31544082
43 + 31544039 = 31544082
61 + 31544021 = 31544082
71 + 31544011 = 31544082
103 + 31543979 = 31544082
179 + 31543903 = 31544082

Showing the first eight; more decompositions exist.
