Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33543140, here are decompositions:

61 + 33543079 = 33543140
73 + 33543067 = 33543140
79 + 33543061 = 33543140
109 + 33543031 = 33543140
157 + 33542983 = 33543140
313 + 33542827 = 33543140
349 + 33542791 = 33543140
487 + 33542653 = 33543140

Showing the first eight; more decompositions exist.
