Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 581764, here are decompositions:

11 + 581753 = 581764
101 + 581663 = 581764
107 + 581657 = 581764
167 + 581597 = 581764
191 + 581573 = 581764
317 + 581447 = 581764
353 + 581411 = 581764
431 + 581333 = 581764

Showing the first eight; more decompositions exist.
