Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474396, here are decompositions:

53 + 31474343 = 31474396
89 + 31474307 = 31474396
179 + 31474217 = 31474396
353 + 31474043 = 31474396
389 + 31474007 = 31474396
419 + 31473977 = 31474396
479 + 31473917 = 31474396
509 + 31473887 = 31474396

Showing the first eight; more decompositions exist.
