Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045972, here are decompositions:

113 + 1045859 = 1045972
131 + 1045841 = 1045972
173 + 1045799 = 1045972
233 + 1045739 = 1045972
281 + 1045691 = 1045972
293 + 1045679 = 1045972
401 + 1045571 = 1045972
443 + 1045529 = 1045972

Showing the first eight; more decompositions exist.
