Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462258, here are decompositions:

41 + 31462217 = 31462258
131 + 31462127 = 31462258
251 + 31462007 = 31462258
281 + 31461977 = 31462258
467 + 31461791 = 31462258
479 + 31461779 = 31462258
521 + 31461737 = 31462258
617 + 31461641 = 31462258

Showing the first eight; more decompositions exist.
