Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 547442, here are decompositions:

31 + 547411 = 547442
43 + 547399 = 547442
73 + 547369 = 547442
79 + 547363 = 547442
151 + 547291 = 547442
193 + 547249 = 547442
271 + 547171 = 547442
349 + 547093 = 547442

Showing the first eight; more decompositions exist.
