Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491642, here are decompositions:

3 + 33491639 = 33491642
43 + 33491599 = 33491642
73 + 33491569 = 33491642
109 + 33491533 = 33491642
181 + 33491461 = 33491642
271 + 33491371 = 33491642
409 + 33491233 = 33491642
421 + 33491221 = 33491642

Showing the first eight; more decompositions exist.
