Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555624, here are decompositions:

31 + 555593 = 555624
67 + 555557 = 555624
101 + 555523 = 555624
103 + 555521 = 555624
137 + 555487 = 555624
163 + 555461 = 555624
233 + 555391 = 555624
241 + 555383 = 555624

Showing the first eight; more decompositions exist.
