Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33511442, here are decompositions:

43 + 33511399 = 33511442
103 + 33511339 = 33511442
193 + 33511249 = 33511442
271 + 33511171 = 33511442
313 + 33511129 = 33511442
541 + 33510901 = 33511442
661 + 33510781 = 33511442
691 + 33510751 = 33511442

Showing the first eight; more decompositions exist.
