Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624010, here are decompositions:

7 + 31624003 = 31624010
31 + 31623979 = 31624010
43 + 31623967 = 31624010
79 + 31623931 = 31624010
109 + 31623901 = 31624010
193 + 31623817 = 31624010
307 + 31623703 = 31624010
421 + 31623589 = 31624010

Showing the first eight; more decompositions exist.
