Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524008, here are decompositions:

67 + 31523941 = 31524008
127 + 31523881 = 31524008
157 + 31523851 = 31524008
349 + 31523659 = 31524008
409 + 31523599 = 31524008
487 + 31523521 = 31524008
541 + 31523467 = 31524008
547 + 31523461 = 31524008

Showing the first eight; more decompositions exist.
