Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496730, here are decompositions:

11 + 31496719 = 31496730
37 + 31496693 = 31496730
53 + 31496677 = 31496730
59 + 31496671 = 31496730
61 + 31496669 = 31496730
131 + 31496599 = 31496730
137 + 31496593 = 31496730
157 + 31496573 = 31496730

Showing the first eight; more decompositions exist.
