Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494074, here are decompositions:

193 + 31493881 = 31494074
223 + 31493851 = 31494074
331 + 31493743 = 31494074
397 + 31493677 = 31494074
421 + 31493653 = 31494074
433 + 31493641 = 31494074
463 + 31493611 = 31494074
541 + 31493533 = 31494074

Showing the first eight; more decompositions exist.
