Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473650, here are decompositions:

67 + 31473583 = 31473650
127 + 31473523 = 31473650
163 + 31473487 = 31473650
193 + 31473457 = 31473650
337 + 31473313 = 31473650
367 + 31473283 = 31473650
409 + 31473241 = 31473650
433 + 31473217 = 31473650

Showing the first eight; more decompositions exist.
