Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462286, here are decompositions:

13 + 31462273 = 31462286
19 + 31462267 = 31462286
283 + 31462003 = 31462286
307 + 31461979 = 31462286
337 + 31461949 = 31462286
367 + 31461919 = 31462286
463 + 31461823 = 31462286
523 + 31461763 = 31462286

Showing the first eight; more decompositions exist.
