Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531142, here are decompositions:

59 + 33531083 = 33531142
83 + 33531059 = 33531142
131 + 33531011 = 33531142
173 + 33530969 = 33531142
353 + 33530789 = 33531142
383 + 33530759 = 33531142
401 + 33530741 = 33531142
773 + 33530369 = 33531142

Showing the first eight; more decompositions exist.
