Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462460, here are decompositions:

19 + 31462441 = 31462460
79 + 31462381 = 31462460
97 + 31462363 = 31462460
103 + 31462357 = 31462460
109 + 31462351 = 31462460
193 + 31462267 = 31462460
439 + 31462021 = 31462460
457 + 31462003 = 31462460

Showing the first eight; more decompositions exist.
