Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1054890, here are decompositions:

37 + 1054853 = 1054890
47 + 1054843 = 1054890
59 + 1054831 = 1054890
71 + 1054819 = 1054890
157 + 1054733 = 1054890
167 + 1054723 = 1054890
173 + 1054717 = 1054890
211 + 1054679 = 1054890

Showing the first eight; more decompositions exist.
