Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947972, here are decompositions:

13 + 947959 = 947972
61 + 947911 = 947972
79 + 947893 = 947972
139 + 947833 = 947972
199 + 947773 = 947972
229 + 947743 = 947972
313 + 947659 = 947972
331 + 947641 = 947972

Showing the first eight; more decompositions exist.
