Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 537778, here are decompositions:

5 + 537773 = 537778
29 + 537749 = 537778
167 + 537611 = 537778
179 + 537599 = 537778
191 + 537587 = 537778
251 + 537527 = 537778
281 + 537497 = 537778
431 + 537347 = 537778

Showing the first eight; more decompositions exist.
