Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473082, here are decompositions:

5 + 31473077 = 31473082
41 + 31473041 = 31473082
191 + 31472891 = 31473082
233 + 31472849 = 31473082
269 + 31472813 = 31473082
359 + 31472723 = 31473082
383 + 31472699 = 31473082
419 + 31472663 = 31473082

Showing the first eight; more decompositions exist.
