Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474202, here are decompositions:

31 + 31474171 = 31474202
61 + 31474141 = 31474202
73 + 31474129 = 31474202
211 + 31473991 = 31474202
271 + 31473931 = 31474202
421 + 31473781 = 31474202
499 + 31473703 = 31474202
619 + 31473583 = 31474202

Showing the first eight; more decompositions exist.
