Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504408, here are decompositions:

41 + 31504367 = 31504408
179 + 31504229 = 31504408
281 + 31504127 = 31504408
311 + 31504097 = 31504408
431 + 31503977 = 31504408
479 + 31503929 = 31504408
491 + 31503917 = 31504408
521 + 31503887 = 31504408

Showing the first eight; more decompositions exist.
