Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481044, here are decompositions:

5 + 31481039 = 31481044
71 + 31480973 = 31481044
131 + 31480913 = 31481044
251 + 31480793 = 31481044
281 + 31480763 = 31481044
311 + 31480733 = 31481044
653 + 31480391 = 31481044
677 + 31480367 = 31481044

Showing the first eight; more decompositions exist.
