Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504430, here are decompositions:

43 + 31504387 = 31504430
73 + 31504357 = 31504430
79 + 31504351 = 31504430
103 + 31504327 = 31504430
127 + 31504303 = 31504430
211 + 31504219 = 31504430
229 + 31504201 = 31504430
241 + 31504189 = 31504430

Showing the first eight; more decompositions exist.
