Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 557900, here are decompositions:

37 + 557863 = 557900
43 + 557857 = 557900
97 + 557803 = 557900
139 + 557761 = 557900
157 + 557743 = 557900
229 + 557671 = 557900
349 + 557551 = 557900
367 + 557533 = 557900

Showing the first eight; more decompositions exist.
