Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452844, here are decompositions:

41 + 31452803 = 31452844
113 + 31452731 = 31452844
167 + 31452677 = 31452844
257 + 31452587 = 31452844
317 + 31452527 = 31452844
347 + 31452497 = 31452844
383 + 31452461 = 31452844
443 + 31452401 = 31452844

Showing the first eight; more decompositions exist.
