Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146972, here are decompositions:

19 + 146953 = 146972
31 + 146941 = 146972
79 + 146893 = 146972
139 + 146833 = 146972
223 + 146749 = 146972
229 + 146743 = 146972
271 + 146701 = 146972
409 + 146563 = 146972

Showing the first eight; more decompositions exist.
