Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462346, here are decompositions:

7 + 31462339 = 31462346
73 + 31462273 = 31462346
79 + 31462267 = 31462346
277 + 31462069 = 31462346
367 + 31461979 = 31462346
397 + 31461949 = 31462346
523 + 31461823 = 31462346
673 + 31461673 = 31462346

Showing the first eight; more decompositions exist.
