Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474046, here are decompositions:

3 + 31474043 = 31474046
13 + 31474033 = 31474046
139 + 31473907 = 31474046
199 + 31473847 = 31474046
313 + 31473733 = 31474046
463 + 31473583 = 31474046
523 + 31473523 = 31474046
733 + 31473313 = 31474046

Showing the first eight; more decompositions exist.
