Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462370, here are decompositions:

7 + 31462363 = 31462370
13 + 31462357 = 31462370
19 + 31462351 = 31462370
31 + 31462339 = 31462370
97 + 31462273 = 31462370
103 + 31462267 = 31462370
229 + 31462141 = 31462370
349 + 31462021 = 31462370

Showing the first eight; more decompositions exist.
