Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 552780, here are decompositions:

23 + 552757 = 552780
29 + 552751 = 552780
31 + 552749 = 552780
71 + 552709 = 552780
73 + 552707 = 552780
103 + 552677 = 552780
131 + 552649 = 552780
191 + 552589 = 552780

Showing the first eight; more decompositions exist.
