Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517174, here are decompositions:

163 + 31517011 = 31517174
181 + 31516993 = 31517174
193 + 31516981 = 31517174
223 + 31516951 = 31517174
397 + 31516777 = 31517174
421 + 31516753 = 31517174
541 + 31516633 = 31517174
547 + 31516627 = 31517174

Showing the first eight; more decompositions exist.
