Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480774, here are decompositions:

5 + 31480769 = 31480774
11 + 31480763 = 31480774
41 + 31480733 = 31480774
383 + 31480391 = 31480774
401 + 31480373 = 31480774
683 + 31480091 = 31480774
827 + 31479947 = 31480774
953 + 31479821 = 31480774

Showing the first eight; more decompositions exist.
