Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496766, here are decompositions:

47 + 31496719 = 31496766
73 + 31496693 = 31496766
89 + 31496677 = 31496766
97 + 31496669 = 31496766
167 + 31496599 = 31496766
173 + 31496593 = 31496766
179 + 31496587 = 31496766
193 + 31496573 = 31496766

Showing the first eight; more decompositions exist.
