Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018972, here are decompositions:

5 + 1018967 = 1018972
23 + 1018949 = 1018972
41 + 1018931 = 1018972
83 + 1018889 = 1018972
113 + 1018859 = 1018972
239 + 1018733 = 1018972
263 + 1018709 = 1018972
293 + 1018679 = 1018972

Showing the first eight; more decompositions exist.
