Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574672, here are decompositions:

109 + 31574563 = 31574672
193 + 31574479 = 31574672
223 + 31574449 = 31574672
229 + 31574443 = 31574672
439 + 31574233 = 31574672
499 + 31574173 = 31574672
541 + 31574131 = 31574672
601 + 31574071 = 31574672

Showing the first eight; more decompositions exist.
