Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544214, here are decompositions:

7 + 31544207 = 31544214
43 + 31544171 = 31544214
47 + 31544167 = 31544214
61 + 31544153 = 31544214
83 + 31544131 = 31544214
137 + 31544077 = 31544214
157 + 31544057 = 31544214
173 + 31544041 = 31544214

Showing the first eight; more decompositions exist.
