Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462362, here are decompositions:

5 + 31462357 = 31462362
11 + 31462351 = 31462362
13 + 31462349 = 31462362
23 + 31462339 = 31462362
73 + 31462289 = 31462362
89 + 31462273 = 31462362
229 + 31462133 = 31462362
293 + 31462069 = 31462362

Showing the first eight; more decompositions exist.
