Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588248, here are decompositions:

47 + 31588201 = 31588248
229 + 31588019 = 31588248
269 + 31587979 = 31588248
337 + 31587911 = 31588248
389 + 31587859 = 31588248
431 + 31587817 = 31588248
449 + 31587799 = 31588248
467 + 31587781 = 31588248

Showing the first eight; more decompositions exist.
