Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456626, here are decompositions:

29 + 31456597 = 31456626
37 + 31456589 = 31456626
79 + 31456547 = 31456626
109 + 31456517 = 31456626
139 + 31456487 = 31456626
197 + 31456429 = 31456626
307 + 31456319 = 31456626
347 + 31456279 = 31456626

Showing the first eight; more decompositions exist.
