Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504514, here are decompositions:

61 + 31504453 = 31504514
127 + 31504387 = 31504514
157 + 31504357 = 31504514
163 + 31504351 = 31504514
211 + 31504303 = 31504514
313 + 31504201 = 31504514
331 + 31504183 = 31504514
463 + 31504051 = 31504514

Showing the first eight; more decompositions exist.
