Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448134, here are decompositions:

23 + 31448111 = 31448134
101 + 31448033 = 31448134
167 + 31447967 = 31448134
173 + 31447961 = 31448134
233 + 31447901 = 31448134
281 + 31447853 = 31448134
383 + 31447751 = 31448134
461 + 31447673 = 31448134

Showing the first eight; more decompositions exist.
