Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522070, here are decompositions:

79 + 31521991 = 31522070
241 + 31521829 = 31522070
277 + 31521793 = 31522070
331 + 31521739 = 31522070
397 + 31521673 = 31522070
421 + 31521649 = 31522070
499 + 31521571 = 31522070
571 + 31521499 = 31522070

Showing the first eight; more decompositions exist.
