Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537084, here are decompositions:

41 + 31537043 = 31537084
83 + 31537001 = 31537084
101 + 31536983 = 31537084
167 + 31536917 = 31537084
263 + 31536821 = 31537084
311 + 31536773 = 31537084
353 + 31536731 = 31537084
563 + 31536521 = 31537084

Showing the first eight; more decompositions exist.
