Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 537668, here are decompositions:

7 + 537661 = 537668
31 + 537637 = 537668
337 + 537331 = 537668
487 + 537181 = 537668
499 + 537169 = 537668
541 + 537127 = 537668
577 + 537091 = 537668
601 + 537067 = 537668

Showing the first eight; more decompositions exist.
