Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487642, here are decompositions:

3 + 33487639 = 33487642
11 + 33487631 = 33487642
131 + 33487511 = 33487642
191 + 33487451 = 33487642
449 + 33487193 = 33487642
479 + 33487163 = 33487642
491 + 33487151 = 33487642
521 + 33487121 = 33487642

Showing the first eight; more decompositions exist.
