Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130972, here are decompositions:

3 + 130969 = 130972
113 + 130859 = 130972
131 + 130841 = 130972
353 + 130619 = 130972
383 + 130589 = 130972
419 + 130553 = 130972
449 + 130523 = 130972
503 + 130469 = 130972

Showing the first eight; more decompositions exist.
