Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605852, here are decompositions:

29 + 31605823 = 31605852
41 + 31605811 = 31605852
43 + 31605809 = 31605852
71 + 31605781 = 31605852
73 + 31605779 = 31605852
79 + 31605773 = 31605852
139 + 31605713 = 31605852
151 + 31605701 = 31605852

Showing the first eight; more decompositions exist.
