Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448092, here are decompositions:

23 + 31448069 = 31448092
59 + 31448033 = 31448092
131 + 31447961 = 31448092
191 + 31447901 = 31448092
239 + 31447853 = 31448092
281 + 31447811 = 31448092
293 + 31447799 = 31448092
419 + 31447673 = 31448092

Showing the first eight; more decompositions exist.
