Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448506, here are decompositions:

59 + 31448447 = 31448506
83 + 31448423 = 31448506
137 + 31448369 = 31448506
197 + 31448309 = 31448506
449 + 31448057 = 31448506
653 + 31447853 = 31448506
839 + 31447667 = 31448506
863 + 31447643 = 31448506

Showing the first eight; more decompositions exist.
