Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540028, here are decompositions:

107 + 539921 = 540028
131 + 539897 = 540028
179 + 539849 = 540028
191 + 539837 = 540028
317 + 539711 = 540028
389 + 539639 = 540028
521 + 539507 = 540028
677 + 539351 = 540028

Showing the first eight; more decompositions exist.
