Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552070, here are decompositions:

13 + 31552057 = 31552070
37 + 31552033 = 31552070
73 + 31551997 = 31552070
211 + 31551859 = 31552070
313 + 31551757 = 31552070
337 + 31551733 = 31552070
349 + 31551721 = 31552070
457 + 31551613 = 31552070

Showing the first eight; more decompositions exist.
