Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532804, here are decompositions:

67 + 31532737 = 31532804
151 + 31532653 = 31532804
211 + 31532593 = 31532804
223 + 31532581 = 31532804
283 + 31532521 = 31532804
307 + 31532497 = 31532804
367 + 31532437 = 31532804
463 + 31532341 = 31532804

Showing the first eight; more decompositions exist.
