Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1039972, here are decompositions:

23 + 1039949 = 1039972
29 + 1039943 = 1039972
41 + 1039931 = 1039972
71 + 1039901 = 1039972
149 + 1039823 = 1039972
173 + 1039799 = 1039972
239 + 1039733 = 1039972
419 + 1039553 = 1039972

Showing the first eight; more decompositions exist.
