Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574162, here are decompositions:

31 + 31574131 = 31574162
163 + 31573999 = 31574162
331 + 31573831 = 31574162
409 + 31573753 = 31574162
523 + 31573639 = 31574162
541 + 31573621 = 31574162
601 + 31573561 = 31574162
661 + 31573501 = 31574162

Showing the first eight; more decompositions exist.
