Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529354, here are decompositions:

7 + 31529347 = 31529354
97 + 31529257 = 31529354
523 + 31528831 = 31529354
541 + 31528813 = 31529354
547 + 31528807 = 31529354
613 + 31528741 = 31529354
631 + 31528723 = 31529354
733 + 31528621 = 31529354

Showing the first eight; more decompositions exist.
