Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604852, here are decompositions:

3 + 31604849 = 31604852
109 + 31604743 = 31604852
163 + 31604689 = 31604852
211 + 31604641 = 31604852
241 + 31604611 = 31604852
541 + 31604311 = 31604852
571 + 31604281 = 31604852
661 + 31604191 = 31604852

Showing the first eight; more decompositions exist.
