Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187562, here are decompositions:

3 + 187559 = 187562
31 + 187531 = 187562
139 + 187423 = 187562
223 + 187339 = 187562
373 + 187189 = 187562
421 + 187141 = 187562
433 + 187129 = 187562
439 + 187123 = 187562

Showing the first eight; more decompositions exist.
