Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501082, here are decompositions:

43 + 31501039 = 31501082
73 + 31501009 = 31501082
103 + 31500979 = 31501082
163 + 31500919 = 31501082
211 + 31500871 = 31501082
229 + 31500853 = 31501082
433 + 31500649 = 31501082
523 + 31500559 = 31501082

Showing the first eight; more decompositions exist.
