Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532404, here are decompositions:

3 + 31532401 = 31532404
263 + 31532141 = 31532404
383 + 31532021 = 31532404
401 + 31532003 = 31532404
521 + 31531883 = 31532404
587 + 31531817 = 31532404
653 + 31531751 = 31532404
677 + 31531727 = 31532404

Showing the first eight; more decompositions exist.
