Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583030, here are decompositions:

7 + 31583023 = 31583030
79 + 31582951 = 31583030
139 + 31582891 = 31583030
211 + 31582819 = 31583030
397 + 31582633 = 31583030
421 + 31582609 = 31583030
499 + 31582531 = 31583030
541 + 31582489 = 31583030

Showing the first eight; more decompositions exist.
