Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555778, here are decompositions:

41 + 33555737 = 33555778
131 + 33555647 = 33555778
149 + 33555629 = 33555778
167 + 33555611 = 33555778
251 + 33555527 = 33555778
281 + 33555497 = 33555778
317 + 33555461 = 33555778
359 + 33555419 = 33555778

Showing the first eight; more decompositions exist.
