Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531580, here are decompositions:

3 + 33531577 = 33531580
53 + 33531527 = 33531580
101 + 33531479 = 33531580
107 + 33531473 = 33531580
113 + 33531467 = 33531580
149 + 33531431 = 33531580
167 + 33531413 = 33531580
191 + 33531389 = 33531580

Showing the first eight; more decompositions exist.
