Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531172, here are decompositions:

5 + 33531167 = 33531172
89 + 33531083 = 33531172
113 + 33531059 = 33531172
173 + 33530999 = 33531172
359 + 33530813 = 33531172
383 + 33530789 = 33531172
431 + 33530741 = 33531172
443 + 33530729 = 33531172

Showing the first eight; more decompositions exist.
