Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31587362, here are decompositions:

73 + 31587289 = 31587362
139 + 31587223 = 31587362
211 + 31587151 = 31587362
271 + 31587091 = 31587362
421 + 31586941 = 31587362
523 + 31586839 = 31587362
571 + 31586791 = 31587362
619 + 31586743 = 31587362

Showing the first eight; more decompositions exist.
