Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1057780, here are decompositions:

41 + 1057739 = 1057780
137 + 1057643 = 1057780
149 + 1057631 = 1057780
167 + 1057613 = 1057780
173 + 1057607 = 1057780
239 + 1057541 = 1057780
293 + 1057487 = 1057780
359 + 1057421 = 1057780

Showing the first eight; more decompositions exist.
