Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606752, here are decompositions:

11 + 31606741 = 31606752
41 + 31606711 = 31606752
61 + 31606691 = 31606752
71 + 31606681 = 31606752
101 + 31606651 = 31606752
109 + 31606643 = 31606752
173 + 31606579 = 31606752
193 + 31606559 = 31606752

Showing the first eight; more decompositions exist.
