Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619662, here are decompositions:

59 + 31619603 = 31619662
101 + 31619561 = 31619662
131 + 31619531 = 31619662
401 + 31619261 = 31619662
449 + 31619213 = 31619662
479 + 31619183 = 31619662
491 + 31619171 = 31619662
653 + 31619009 = 31619662

Showing the first eight; more decompositions exist.
