Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690972, here are decompositions:

13 + 8690959 = 8690972
19 + 8690953 = 8690972
151 + 8690821 = 8690972
313 + 8690659 = 8690972
373 + 8690599 = 8690972
379 + 8690593 = 8690972
421 + 8690551 = 8690972
601 + 8690371 = 8690972

Showing the first eight; more decompositions exist.
