Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33488442, here are decompositions:

61 + 33488381 = 33488442
73 + 33488369 = 33488442
89 + 33488353 = 33488442
109 + 33488333 = 33488442
131 + 33488311 = 33488442
139 + 33488303 = 33488442
241 + 33488201 = 33488442
311 + 33488131 = 33488442

Showing the first eight; more decompositions exist.
