Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528184, here are decompositions:

13 + 31528171 = 31528184
73 + 31528111 = 31528184
271 + 31527913 = 31528184
367 + 31527817 = 31528184
397 + 31527787 = 31528184
487 + 31527697 = 31528184
601 + 31527583 = 31528184
607 + 31527577 = 31528184

Showing the first eight; more decompositions exist.
