Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504262, here are decompositions:

43 + 31504219 = 31504262
61 + 31504201 = 31504262
73 + 31504189 = 31504262
79 + 31504183 = 31504262
211 + 31504051 = 31504262
331 + 31503931 = 31504262
379 + 31503883 = 31504262
409 + 31503853 = 31504262

Showing the first eight; more decompositions exist.
