Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 547642, here are decompositions:

3 + 547639 = 547642
23 + 547619 = 547642
41 + 547601 = 547642
59 + 547583 = 547642
83 + 547559 = 547642
113 + 547529 = 547642
149 + 547493 = 547642
269 + 547373 = 547642

Showing the first eight; more decompositions exist.
