Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620752, here are decompositions:

3 + 31620749 = 31620752
19 + 31620733 = 31620752
43 + 31620709 = 31620752
73 + 31620679 = 31620752
151 + 31620601 = 31620752
181 + 31620571 = 31620752
271 + 31620481 = 31620752
409 + 31620343 = 31620752

Showing the first eight; more decompositions exist.
