Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447324, here are decompositions:

23 + 31447301 = 31447324
71 + 31447253 = 31447324
107 + 31447217 = 31447324
113 + 31447211 = 31447324
191 + 31447133 = 31447324
281 + 31447043 = 31447324
431 + 31446893 = 31447324
563 + 31446761 = 31447324

Showing the first eight; more decompositions exist.
