Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544084, here are decompositions:

7 + 31544077 = 31544084
31 + 31544053 = 31544084
43 + 31544041 = 31544084
73 + 31544011 = 31544084
97 + 31543987 = 31544084
157 + 31543927 = 31544084
181 + 31543903 = 31544084
211 + 31543873 = 31544084

Showing the first eight; more decompositions exist.
