Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528226, here are decompositions:

13 + 31528213 = 31528226
19 + 31528207 = 31528226
157 + 31528069 = 31528226
229 + 31527997 = 31528226
313 + 31527913 = 31528226
397 + 31527829 = 31528226
409 + 31527817 = 31528226
439 + 31527787 = 31528226

Showing the first eight; more decompositions exist.
