Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544138, here are decompositions:

7 + 31544131 = 31544138
61 + 31544077 = 31544138
97 + 31544041 = 31544138
127 + 31544011 = 31544138
151 + 31543987 = 31544138
211 + 31543927 = 31544138
607 + 31543531 = 31544138
709 + 31543429 = 31544138

Showing the first eight; more decompositions exist.
