Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473422, here are decompositions:

109 + 31473313 = 31473422
139 + 31473283 = 31473422
181 + 31473241 = 31473422
271 + 31473151 = 31473422
313 + 31473109 = 31473422
439 + 31472983 = 31473422
571 + 31472851 = 31473422
811 + 31472611 = 31473422

Showing the first eight; more decompositions exist.
