Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757844, here are decompositions:

23 + 8757821 = 8757844
131 + 8757713 = 8757844
281 + 8757563 = 8757844
317 + 8757527 = 8757844
467 + 8757377 = 8757844
503 + 8757341 = 8757844
653 + 8757191 = 8757844
701 + 8757143 = 8757844

Showing the first eight; more decompositions exist.
