Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620652, here are decompositions:

53 + 31620599 = 31620652
71 + 31620581 = 31620652
83 + 31620569 = 31620652
131 + 31620521 = 31620652
179 + 31620473 = 31620652
293 + 31620359 = 31620652
353 + 31620299 = 31620652
383 + 31620269 = 31620652

Showing the first eight; more decompositions exist.
