Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620546, here are decompositions:

29 + 31620517 = 31620546
47 + 31620499 = 31620546
59 + 31620487 = 31620546
73 + 31620473 = 31620546
103 + 31620443 = 31620546
137 + 31620409 = 31620546
149 + 31620397 = 31620546
229 + 31620317 = 31620546

Showing the first eight; more decompositions exist.
