Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462412, here are decompositions:

31 + 31462381 = 31462412
61 + 31462351 = 31462412
73 + 31462339 = 31462412
139 + 31462273 = 31462412
271 + 31462141 = 31462412
409 + 31462003 = 31462412
433 + 31461979 = 31462412
463 + 31461949 = 31462412

Showing the first eight; more decompositions exist.
