Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474092, here are decompositions:

19 + 31474073 = 31474092
31 + 31474061 = 31474092
59 + 31474033 = 31474092
101 + 31473991 = 31474092
191 + 31473901 = 31474092
229 + 31473863 = 31474092
281 + 31473811 = 31474092
283 + 31473809 = 31474092

Showing the first eight; more decompositions exist.
