Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448038, here are decompositions:

5 + 31448033 = 31448038
71 + 31447967 = 31448038
107 + 31447931 = 31448038
137 + 31447901 = 31448038
227 + 31447811 = 31448038
239 + 31447799 = 31448038
269 + 31447769 = 31448038
431 + 31447607 = 31448038

Showing the first eight; more decompositions exist.
