Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 544538, here are decompositions:

37 + 544501 = 544538
61 + 544477 = 544538
67 + 544471 = 544538
109 + 544429 = 544538
139 + 544399 = 544538
367 + 544171 = 544538
409 + 544129 = 544538
439 + 544099 = 544538

Showing the first eight; more decompositions exist.
