Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 537444, here are decompositions:

31 + 537413 = 537444
41 + 537403 = 537444
43 + 537401 = 537444
71 + 537373 = 537444
97 + 537347 = 537444
101 + 537343 = 537444
113 + 537331 = 537444
137 + 537307 = 537444

Showing the first eight; more decompositions exist.
