Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583132, here are decompositions:

109 + 31583023 = 31583132
151 + 31582981 = 31583132
181 + 31582951 = 31583132
241 + 31582891 = 31583132
313 + 31582819 = 31583132
499 + 31582633 = 31583132
523 + 31582609 = 31583132
601 + 31582531 = 31583132

Showing the first eight; more decompositions exist.
