Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003730, here are decompositions:

19 + 1003711 = 1003730
37 + 1003693 = 1003730
103 + 1003627 = 1003730
109 + 1003621 = 1003730
181 + 1003549 = 1003730
223 + 1003507 = 1003730
313 + 1003417 = 1003730
349 + 1003381 = 1003730

Showing the first eight; more decompositions exist.
