Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 537442, here are decompositions:

29 + 537413 = 537442
41 + 537401 = 537442
173 + 537269 = 537442
251 + 537191 = 537442
401 + 537041 = 537442
419 + 537023 = 537442
431 + 537011 = 537442
443 + 536999 = 537442

Showing the first eight; more decompositions exist.
