Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 537780, here are decompositions:

7 + 537773 = 537780
11 + 537769 = 537780
31 + 537749 = 537780
37 + 537743 = 537780
41 + 537739 = 537780
71 + 537709 = 537780
101 + 537679 = 537780
107 + 537673 = 537780

Showing the first eight; more decompositions exist.
