Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529066, here are decompositions:

13 + 31529053 = 31529066
73 + 31528993 = 31529066
97 + 31528969 = 31529066
157 + 31528909 = 31529066
223 + 31528843 = 31529066
337 + 31528729 = 31529066
397 + 31528669 = 31529066
433 + 31528633 = 31529066

Showing the first eight; more decompositions exist.
