Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523012, here are decompositions:

61 + 31522951 = 31523012
139 + 31522873 = 31523012
349 + 31522663 = 31523012
379 + 31522633 = 31523012
421 + 31522591 = 31523012
463 + 31522549 = 31523012
571 + 31522441 = 31523012
601 + 31522411 = 31523012

Showing the first eight; more decompositions exist.
