Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540184, here are decompositions:

3 + 31540181 = 31540184
37 + 31540147 = 31540184
61 + 31540123 = 31540184
283 + 31539901 = 31540184
367 + 31539817 = 31540184
421 + 31539763 = 31540184
457 + 31539727 = 31540184
523 + 31539661 = 31540184

Showing the first eight; more decompositions exist.
