Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474282, here are decompositions:

29 + 31474253 = 31474282
239 + 31474043 = 31474282
311 + 31473971 = 31474282
419 + 31473863 = 31474282
443 + 31473839 = 31474282
503 + 31473779 = 31474282
683 + 31473599 = 31474282
701 + 31473581 = 31474282

Showing the first eight; more decompositions exist.
