Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525010, here are decompositions:

3 + 31525007 = 31525010
19 + 31524991 = 31525010
43 + 31524967 = 31525010
73 + 31524937 = 31525010
337 + 31524673 = 31525010
367 + 31524643 = 31525010
487 + 31524523 = 31525010
541 + 31524469 = 31525010

Showing the first eight; more decompositions exist.
