Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587890, here are decompositions:

23 + 33587867 = 33587890
59 + 33587831 = 33587890
101 + 33587789 = 33587890
257 + 33587633 = 33587890
353 + 33587537 = 33587890
383 + 33587507 = 33587890
419 + 33587471 = 33587890
569 + 33587321 = 33587890

Showing the first eight; more decompositions exist.
