Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33547142, here are decompositions:

3 + 33547139 = 33547142
61 + 33547081 = 33547142
271 + 33546871 = 33547142
313 + 33546829 = 33547142
439 + 33546703 = 33547142
613 + 33546529 = 33547142
631 + 33546511 = 33547142
691 + 33546451 = 33547142

Showing the first eight; more decompositions exist.
