Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624004, here are decompositions:

3 + 31624001 = 31624004
37 + 31623967 = 31624004
73 + 31623931 = 31624004
103 + 31623901 = 31624004
283 + 31623721 = 31624004
337 + 31623667 = 31624004
397 + 31623607 = 31624004
523 + 31623481 = 31624004

Showing the first eight; more decompositions exist.
