Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534860, here are decompositions:

29 + 31534831 = 31534860
41 + 31534819 = 31534860
59 + 31534801 = 31534860
61 + 31534799 = 31534860
73 + 31534787 = 31534860
103 + 31534757 = 31534860
107 + 31534753 = 31534860
109 + 31534751 = 31534860

Showing the first eight; more decompositions exist.
