Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474244, here are decompositions:

31 + 31474213 = 31474244
73 + 31474171 = 31474244
103 + 31474141 = 31474244
211 + 31474033 = 31474244
313 + 31473931 = 31474244
337 + 31473907 = 31474244
397 + 31473847 = 31474244
433 + 31473811 = 31474244

Showing the first eight; more decompositions exist.
