Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055870, here are decompositions:

3 + 1055867 = 1055870
7 + 1055863 = 1055870
19 + 1055851 = 1055870
31 + 1055839 = 1055870
43 + 1055827 = 1055870
61 + 1055809 = 1055870
139 + 1055731 = 1055870
157 + 1055713 = 1055870

Showing the first eight; more decompositions exist.
