Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529174, here are decompositions:

7 + 31529167 = 31529174
67 + 31529107 = 31529174
181 + 31528993 = 31529174
331 + 31528843 = 31529174
367 + 31528807 = 31529174
373 + 31528801 = 31529174
433 + 31528741 = 31529174
541 + 31528633 = 31529174

Showing the first eight; more decompositions exist.
