Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529234, here are decompositions:

67 + 31529167 = 31529234
127 + 31529107 = 31529234
181 + 31529053 = 31529234
241 + 31528993 = 31529234
421 + 31528813 = 31529234
433 + 31528801 = 31529234
601 + 31528633 = 31529234
613 + 31528621 = 31529234

Showing the first eight; more decompositions exist.
