Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504302, here are decompositions:

73 + 31504229 = 31504302
83 + 31504219 = 31504302
101 + 31504201 = 31504302
113 + 31504189 = 31504302
173 + 31504129 = 31504302
199 + 31504103 = 31504302
251 + 31504051 = 31504302
331 + 31503971 = 31504302

Showing the first eight; more decompositions exist.
