Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 537980, here are decompositions:

61 + 537919 = 537980
67 + 537913 = 537980
97 + 537883 = 537980
103 + 537877 = 537980
127 + 537853 = 537980
139 + 537841 = 537980
193 + 537787 = 537980
199 + 537781 = 537980

Showing the first eight; more decompositions exist.
