Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504458, here are decompositions:

5 + 31504453 = 31504458
19 + 31504439 = 31504458
71 + 31504387 = 31504458
101 + 31504357 = 31504458
107 + 31504351 = 31504458
131 + 31504327 = 31504458
229 + 31504229 = 31504458
239 + 31504219 = 31504458

Showing the first eight; more decompositions exist.
