Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528352, here are decompositions:

3 + 31528349 = 31528352
61 + 31528291 = 31528352
73 + 31528279 = 31528352
139 + 31528213 = 31528352
181 + 31528171 = 31528352
241 + 31528111 = 31528352
283 + 31528069 = 31528352
421 + 31527931 = 31528352

Showing the first eight; more decompositions exist.
