Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552166, here are decompositions:

97 + 31552069 = 31552166
109 + 31552057 = 31552166
229 + 31551937 = 31552166
307 + 31551859 = 31552166
313 + 31551853 = 31552166
409 + 31551757 = 31552166
433 + 31551733 = 31552166
619 + 31551547 = 31552166

Showing the first eight; more decompositions exist.
