Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601498, here are decompositions:

139 + 31601359 = 31601498
151 + 31601347 = 31601498
157 + 31601341 = 31601498
307 + 31601191 = 31601498
421 + 31601077 = 31601498
457 + 31601041 = 31601498
541 + 31600957 = 31601498
727 + 31600771 = 31601498

Showing the first eight; more decompositions exist.
