Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552836, here are decompositions:

5 + 31552831 = 31552836
19 + 31552817 = 31552836
89 + 31552747 = 31552836
103 + 31552733 = 31552836
109 + 31552727 = 31552836
127 + 31552709 = 31552836
193 + 31552643 = 31552836
197 + 31552639 = 31552836

Showing the first eight; more decompositions exist.
