Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528954, here are decompositions:

101 + 31528853 = 31528954
113 + 31528841 = 31528954
131 + 31528823 = 31528954
257 + 31528697 = 31528954
503 + 31528451 = 31528954
521 + 31528433 = 31528954
617 + 31528337 = 31528954
641 + 31528313 = 31528954

Showing the first eight; more decompositions exist.
