Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469886, here are decompositions:

29 + 31469857 = 31469886
37 + 31469849 = 31469886
73 + 31469813 = 31469886
89 + 31469797 = 31469886
103 + 31469783 = 31469886
163 + 31469723 = 31469886
197 + 31469689 = 31469886
233 + 31469653 = 31469886

Showing the first eight; more decompositions exist.
