Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504480, here are decompositions:

41 + 31504439 = 31504480
107 + 31504373 = 31504480
113 + 31504367 = 31504480
251 + 31504229 = 31504480
347 + 31504133 = 31504480
353 + 31504127 = 31504480
383 + 31504097 = 31504480
443 + 31504037 = 31504480

Showing the first eight; more decompositions exist.
