Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 555988, here are decompositions:

47 + 555941 = 555988
131 + 555857 = 555988
227 + 555761 = 555988
281 + 555707 = 555988
311 + 555677 = 555988
317 + 555671 = 555988
431 + 555557 = 555988
467 + 555521 = 555988

Showing the first eight; more decompositions exist.
