Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620536, here are decompositions:

19 + 31620517 = 31620536
37 + 31620499 = 31620536
127 + 31620409 = 31620536
139 + 31620397 = 31620536
193 + 31620343 = 31620536
307 + 31620229 = 31620536
313 + 31620223 = 31620536
397 + 31620139 = 31620536

Showing the first eight; more decompositions exist.
