Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462246, here are decompositions:

29 + 31462217 = 31462246
113 + 31462133 = 31462246
239 + 31462007 = 31462246
269 + 31461977 = 31462246
353 + 31461893 = 31462246
359 + 31461887 = 31462246
467 + 31461779 = 31462246
503 + 31461743 = 31462246

Showing the first eight; more decompositions exist.
