Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33497642, here are decompositions:

19 + 33497623 = 33497642
193 + 33497449 = 33497642
223 + 33497419 = 33497642
229 + 33497413 = 33497642
331 + 33497311 = 33497642
571 + 33497071 = 33497642
613 + 33497029 = 33497642
733 + 33496909 = 33497642

Showing the first eight; more decompositions exist.
