Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601236, here are decompositions:

137 + 31601099 = 31601236
353 + 31600883 = 31601236
419 + 31600817 = 31601236
503 + 31600733 = 31601236
617 + 31600619 = 31601236
743 + 31600493 = 31601236
827 + 31600409 = 31601236
929 + 31600307 = 31601236

Showing the first eight; more decompositions exist.
