Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33488138, here are decompositions:

7 + 33488131 = 33488138
31 + 33488107 = 33488138
37 + 33488101 = 33488138
97 + 33488041 = 33488138
139 + 33487999 = 33488138
367 + 33487771 = 33488138
379 + 33487759 = 33488138
421 + 33487717 = 33488138

Showing the first eight; more decompositions exist.
