Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33472642, here are decompositions:

3 + 33472639 = 33472642
53 + 33472589 = 33472642
89 + 33472553 = 33472642
149 + 33472493 = 33472642
311 + 33472331 = 33472642
419 + 33472223 = 33472642
449 + 33472193 = 33472642
461 + 33472181 = 33472642

Showing the first eight; more decompositions exist.
