Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496684, here are decompositions:

7 + 31496677 = 31496684
13 + 31496671 = 31496684
73 + 31496611 = 31496684
97 + 31496587 = 31496684
313 + 31496371 = 31496684
367 + 31496317 = 31496684
421 + 31496263 = 31496684
463 + 31496221 = 31496684

Showing the first eight; more decompositions exist.
