Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3550, here are decompositions:

3 + 3547 = 3550
11 + 3539 = 3550
17 + 3533 = 3550
23 + 3527 = 3550
59 + 3491 = 3550
83 + 3467 = 3550
89 + 3461 = 3550
101 + 3449 = 3550

Showing the first eight; more decompositions exist.
