Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 537800, here are decompositions:

7 + 537793 = 537800
13 + 537787 = 537800
19 + 537781 = 537800
31 + 537769 = 537800
61 + 537739 = 537800
97 + 537703 = 537800
127 + 537673 = 537800
139 + 537661 = 537800

Showing the first eight; more decompositions exist.
