Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33485788, here are decompositions:

47 + 33485741 = 33485788
71 + 33485717 = 33485788
101 + 33485687 = 33485788
251 + 33485537 = 33485788
311 + 33485477 = 33485788
389 + 33485399 = 33485788
419 + 33485369 = 33485788
449 + 33485339 = 33485788

Showing the first eight; more decompositions exist.
