Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578642, here are decompositions:

43 + 33578599 = 33578642
73 + 33578569 = 33578642
109 + 33578533 = 33578642
193 + 33578449 = 33578642
199 + 33578443 = 33578642
373 + 33578269 = 33578642
523 + 33578119 = 33578642
631 + 33578011 = 33578642

Showing the first eight; more decompositions exist.
