Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31587092, here are decompositions:

73 + 31587019 = 31587092
151 + 31586941 = 31587092
223 + 31586869 = 31587092
283 + 31586809 = 31587092
349 + 31586743 = 31587092
373 + 31586719 = 31587092
421 + 31586671 = 31587092
619 + 31586473 = 31587092

Showing the first eight; more decompositions exist.
