Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 537428, here are decompositions:

97 + 537331 = 537428
271 + 537157 = 537428
337 + 537091 = 537428
349 + 537079 = 537428
421 + 537007 = 537428
439 + 536989 = 537428
457 + 536971 = 537428
499 + 536929 = 537428

Showing the first eight; more decompositions exist.
