Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031870, here are decompositions:

61 + 1031809 = 1031870
109 + 1031761 = 1031870
139 + 1031731 = 1031870
163 + 1031707 = 1031870
193 + 1031677 = 1031870
241 + 1031629 = 1031870
277 + 1031593 = 1031870
337 + 1031533 = 1031870

Showing the first eight; more decompositions exist.
