Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496742, here are decompositions:

23 + 31496719 = 31496742
71 + 31496671 = 31496742
73 + 31496669 = 31496742
131 + 31496611 = 31496742
149 + 31496593 = 31496742
191 + 31496551 = 31496742
223 + 31496519 = 31496742
293 + 31496449 = 31496742

Showing the first eight; more decompositions exist.
