Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504292, here are decompositions:

73 + 31504219 = 31504292
103 + 31504189 = 31504292
109 + 31504183 = 31504292
163 + 31504129 = 31504292
241 + 31504051 = 31504292
331 + 31503961 = 31504292
409 + 31503883 = 31504292
439 + 31503853 = 31504292

Showing the first eight; more decompositions exist.
