Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473854, here are decompositions:

7 + 31473847 = 31473854
43 + 31473811 = 31473854
73 + 31473781 = 31473854
151 + 31473703 = 31473854
271 + 31473583 = 31473854
331 + 31473523 = 31473854
367 + 31473487 = 31473854
397 + 31473457 = 31473854

Showing the first eight; more decompositions exist.
