Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462376, here are decompositions:

3 + 31462373 = 31462376
13 + 31462363 = 31462376
19 + 31462357 = 31462376
37 + 31462339 = 31462376
103 + 31462273 = 31462376
109 + 31462267 = 31462376
307 + 31462069 = 31462376
373 + 31462003 = 31462376

Showing the first eight; more decompositions exist.
