Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552172, here are decompositions:

103 + 31552069 = 31552172
139 + 31552033 = 31552172
193 + 31551979 = 31552172
271 + 31551901 = 31552172
313 + 31551859 = 31552172
439 + 31551733 = 31552172
811 + 31551361 = 31552172
823 + 31551349 = 31552172

Showing the first eight; more decompositions exist.
