Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544204, here are decompositions:

37 + 31544167 = 31544204
73 + 31544131 = 31544204
127 + 31544077 = 31544204
151 + 31544053 = 31544204
163 + 31544041 = 31544204
193 + 31544011 = 31544204
277 + 31543927 = 31544204
331 + 31543873 = 31544204

Showing the first eight; more decompositions exist.
