Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472442, here are decompositions:

31 + 472411 = 472442
43 + 472399 = 472442
73 + 472369 = 472442
109 + 472333 = 472442
181 + 472261 = 472442
193 + 472249 = 472442
283 + 472159 = 472442
331 + 472111 = 472442

Showing the first eight; more decompositions exist.
