Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487780, here are decompositions:

23 + 33487757 = 33487780
47 + 33487733 = 33487780
149 + 33487631 = 33487780
173 + 33487607 = 33487780
269 + 33487511 = 33487780
461 + 33487319 = 33487780
467 + 33487313 = 33487780
479 + 33487301 = 33487780

Showing the first eight; more decompositions exist.
