Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448236, here are decompositions:

3 + 31448233 = 31448236
167 + 31448069 = 31448236
179 + 31448057 = 31448236
269 + 31447967 = 31448236
383 + 31447853 = 31448236
467 + 31447769 = 31448236
563 + 31447673 = 31448236
569 + 31447667 = 31448236

Showing the first eight; more decompositions exist.
